GENERAL INFORMATION

     The enclosed proxy is being solicited on behalf of the Board of Directors
of UniFirst Corporation (the "Company" or "UniFirst") for use at the 2003 Annual
Meeting of Shareholders to be held on January 14, 2003 (the "Annual Meeting")
and at any adjournment thereof. This Proxy Statement, the enclosed proxy and the
Company's 2002 Annual Report to Shareholders are being mailed to shareholders on
or about December 11, 2002. Any shareholder signing and returning the enclosed
proxy has the power to revoke it by giving notice of its revocation to the
Company in writing or in the open meeting before any vote with respect to the
matters set forth therein is taken. The shares represented by the enclosed proxy
will be voted as specified therein if said proxy is properly signed and received
by the Company prior to the time of the Annual Meeting and is not properly
revoked. The expense of this proxy solicitation will be borne by the Company. In
addition to the solicitation of proxies by mail, the Directors, officers and
employees of the Company may also solicit proxies personally or by telephone
without special compensation for such activities. The Company may also request
persons, firms and corporations holding shares in their names or in the names of
their nominees, which are beneficially owned by others, to send proxy material
to and obtain proxies from such beneficial owners. The Company will reimburse
such holders for their reasonable expenses in connection therewith.

     The Board of Directors has fixed the close of business on November 15, 2002
as the record date for the determination of the shareholders entitled to notice
of, and to vote at, this Annual Meeting and any adjournments thereof. As of the
close of business on that date, there were outstanding and entitled to vote
9,021,179 shares of common stock, par value $.10 per share ("Common Stock"), and
10,205,144 shares of Class B common stock, par value $.10 per share ("Class B
Common Stock"). Transferees after such date will not be entitled to vote at the
Annual Meeting. Each share of Common Stock is entitled to one vote per share.
Each share of Class B Common Stock is entitled to ten votes per share. All
actions submitted to a vote of shareholders are voted on by holders of Common
Stock and Class B Common Stock voting together as a single class, except for the
election of certain Directors and for the approval of matters requiring class
votes under the Business Corporation Law of The Commonwealth of Massachusetts.


                           1.  ELECTION OF DIRECTORS

     The Board of Directors of the Company is currently composed of six members,
divided into three equal classes, with one class elected each year at the annual
meeting of shareholders. The Directors in each class serve for a term of three
years and until their successors are duly elected and qualified. As the term of
one class expires, a successor class is elected at each annual meeting of
shareholders.

     At the Annual Meeting, two Class I Directors will be elected to serve until
the 2006 annual meeting and until their successors are duly elected and
qualified. The Board of Directors has nominated Albert Cohen to be elected by
holders of Common Stock, voting separately as a single class, and Anthony F.
DiFillippo to be elected by holders of Common Stock and Class B Common Stock,
voting together as a single class, to serve as Class I Directors (collectively,
the "Nominees").

     Unless otherwise instructed, the persons named in the proxy will vote the
shares to which the proxy relates "FOR" the election of the Nominees to the
Board of Directors. While the Company has no reason to believe that any of the
Nominees will be unable to serve as a Director, in the event any of the Nominees
should become unavailable to serve at the time of the Annual Meeting, it is the
intention of the persons named in the enclosed proxy to vote such proxy for such
other person or persons as they may in their discretion select. A plurality of
the votes cast by holders of shares of Common Stock, voting separately as a
single class and represented in person or by proxy at the Annual Meeting and
entitled to vote thereon, is necessary to elect Albert Cohen. A plurality of the
votes cast by holders of shares of Common Stock and Class B Common Stock, voting
together as a single class and represented in person or by proxy at the Annual
Meeting and entitled to vote thereon, is necessary to elect Anthony F.
DiFillippo. Consistent with applicable law, the Company intends to count
abstentions and broker non-votes only for the purpose of determining the
presence or absence of a quorum for the transaction of business. Any shares not
voted (whether by abstention, broker non-vote or otherwise) will have no impact
on the election of Directors, except to the extent that the failure to vote for
an individual results in another individual receiving a larger percentage of
votes.

     The following table sets forth certain information with respect to the
Nominees as well as the other Directors of the Company.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Officers, Directors and greater than 10% shareholders are required to file
with the Securities and Exchange Commission pursuant to Section 16(a) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), reports of
ownership and changes in ownership. Such reports are filed on Form 3, Form 4 and
Form 5 under the Exchange Act, as appropriate. Officers, Directors and greater
than 10% shareholders are required by Exchange Act regulations to furnish the
Company with copies of all Section 16(a) forms they file.

     To the Company's knowledge, based solely on review of the copies of such
reports furnished to the Company or written representations that no such reports
were required during the 2002 fiscal year, the Company believes that, during the
2002 fiscal year, all officers, Directors and greater than 10% shareholders

Form 5 filings, and each of Marie Croatti, The Marie Croatti QTIP Trust, the
Estate of Aldo Croatti, The Croatti Family Limited Partnership and Croatti
Management Associates, Inc. inadvertently filed a Form 3 late.

related services

Albert Cohen and Donald J. Evans and met on one occasion. On October 4, 2001,
Aldo Croatti passed away. His position on the Compensation Committee was filled
by Ronald D. Croatti on January 8, 2002. On November 11, 2002, Phillip L. Cohen
replaced Ronald D. Croatti on the Compensation Committee. As of the date of this
proxy statement, the Compensation Committee consists of Albert Cohen (Chairman),
Phillip L. Cohen, and Donald J. Evans. The Compensation Committee is responsible
for reviewing and approving the Company's executive compensation program. As of
the date of this proxy statement, the Company has formed a Nominating and
Corporate Governance Committee consisting of Donald J. Evans (Chairman), Albert
Cohen and Phillip L. Cohen. The Nominating and Corporate Governance Committee
reviews and evaluates potential nominees for election or appointment to the
Board of Directors and recommends such nominees to the full Board of Directors.
The Nominating and Corporate Governance Committee will consider a nominee for
election to the Board of Directors recommended by a shareholder of record if the
shareholder submits the nomination in compliance with the requirements of the
Company's By-laws. See "Other Matters - Shareholder Proposals" for a summary of
these requirements. The Nominating and Corporate Governance Committee is also
responsible for developing and recommending to the Board of Directors a set of
corporate governance guidelines applicable to the Company and periodically
reviewing such guidelines and recommending any changes to those guidelines to
the Board of Directors.

     Each Director attended at least 75% of all of the meetings of the Board of
Directors and of the committees of which the Director was a member held during
the last fiscal year.

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

     The Company maintains the UniFirst Unfunded Supplemental Executive
Retirement Plan (the "SERP") available to certain eligible employees of the
Company and its affiliates. Retirement benefits available under the SERP are
based on a participant's average annual base earnings for the last three years
of employment prior to his retirement date ("Final Average Earnings"). Upon the
retirement of a participant on his social security retirement date, the
participant will be paid an aggregate amount equal to 2.4 times his Final
Average Earnings over a twelve year period. Upon the death of a participant, the
participant's designated beneficiary will be paid retirement benefits as above
(determined as of the date of death if pre-retirement). The SERP provides that,
upon any change of control, retirement benefits of participants who are age 50
or

                                        9


over and whose employment is terminated within three years of the change of
control will become vested and payable, subject to certain years of service
requirements.

    participant's average base salary for the last three years of full-time

                        REPORT OF COMPENSATION COMMITTEE

     At the beginning of the 2002 fiscal year, the Compensation Committee
initially consisted of Albert Cohen and Donald J. Evans, two Directors who are
not employees of the Company, and Aldo Croatti, Chairman. On October 4, 2001,
Aldo Croatti passed away. His position on the Compensation Committee was filled
temporarily by Ronald D. Croatti on January 8, 2002. As of the date of this
proxy statement, the Compensation Committee consists of Albert Cohen, Chairman,
Phillip L. Cohen and Donald J. Evans, three Directors who are not employees of
the Company. The Compensation Committee reviews and approves the Company's
executive compensation program.

COMPENSATION PHILOSOPHY

     The Company seeks to attract and retain executive officers who, in the
judgment of the Company's Board of Directors, possess the skill, experience and
motivation to contribute significantly to the long-term success of the Company
and to long-term stock price appreciation. With this philosophy in mind, the
Compensation Committee follows an executive officer compensation program
designed to foster the mutuality of interest between the Company's executive
officers and the Company's shareholders and to provide senior management
additional incentive to enhance the sales growth and profitability of the
Company, and thus shareholder value.

     The Compensation Committee reviews its compensation policy annually.
Compensation of executive officers currently consists of a base salary and,
based on the achievement of predetermined corporate performance objectives, a
cash bonus. In addition, for fiscal 2002 the Company issued options to purchase
a total of approximately 56,000 shares to over 80 officers, general managers and
other management personnel. Although the Company's fiscal year ends in August,
compensation decisions generally are made on a calendar year basis.

BASE SALARY

     Each year, the Compensation Committee consults with the Chief Executive
Officer with respect to setting the base salaries of its executive officers,
other than the Chief Executive Officer, for the ensuing year. Annual salary
adjustments are determined by evaluating the financial performance of the
Company during the prior year, each executive officer's contribution to the
profitability, sales growth, return on equity and market share of the Company
during the prior year and the compensation programs and levels generally paid to
executives at other companies.

                                        10


INCENTIVE COMPENSATION PLAN

     Annual cash bonuses for executive officers of the Company are determined in
accordance with the Company's incentive compensation plan, the philosophy and
substantive requirements of which are reviewed by the Compensation Committee
each year. Cash bonuses are determined with reference to the Company's financial
performance as measured by growth in revenues and earnings per share and by the
Company's customer retention levels.

     Each year, the Compensation Committee confers with the Chief Executive
Officer and establishes performance goals for revenues, earnings per share and
customer retention. In its determination of the amount of cash bonuses, the
Compensation Committee places primary emphasis on growth in earnings per share
and lesser emphasis on revenue growth and customer retention. The cash bonuses
awarded depend on the extent to which the performance of the Company meets or
exceeds the budgeted amounts. In addition, the Compensation Committee
establishes minimum achievement thresholds and maximum bonus levels for each of
these performance criteria which apply uniformly to the Company's executive
officers. Bonuses are determined and paid annually after the end of each fiscal
year.

COMPENSATION OF CHIEF EXECUTIVE OFFICER

     The Compensation Committee established the compensation of Ronald D.
Croatti, the Chief Executive Officer, for 2002 using the same criteria
applicable to determining compensation levels and bonuses for other executive
officers as noted in this report. Such criteria included the financial
performance of the Company during the 2001 fiscal year, the compensation levels
generally paid to executives of other companies, and Mr. Croatti's contribution
to the profitability, sales growth, return on equity and market share of the
Company during the 2001 fiscal year and his leadership of the Company.
Notwithstanding his substantial contributions in each of these areas, Mr.
Croatti recommended that he not receive any increase in his salary level. He
noted that a significant portion of each senior executive's compensation is tied
to the bonus program and that by freezing his salary, it would set an excellent
leadership example which would be positive for employee morale and further
incentivize the senior executives to achieve the performance goals set forth
under the bonus program. The Compensation Committee accepted and approved Mr.
Croatti's recommendation and Mr. Croatti's 2002 calendar year base salary was
established at $350,000, the same as in the prior year.

                                          Phillip L. Cohen
                                          Donald J. Evans

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Aldo Croatti, founder of the Company, was, during fiscal year 2002, until
his death on October 4, 2001, a member of the Compensation Committee. Ronald D.
Croatti, President and Chief Executive Officer of the Company, was, during
fiscal year 2002, a member of the Compensation Committee. The Company is not
aware of any compensation committee interlocks.

                           REPORT OF AUDIT COMMITTEE

     The Audit Committee has:

     - Reviewed and discussed the audited financial statements with management.

     - Discussed with the independent auditors the matters required to be
       discussed by SAS 61.

     - Received the written disclosures and the letter from the independent
       auditors required by Independence Standards Board Standard No. 1, and has
       discussed with the independent auditors the auditors' independence.

     - Based on the review and discussions above, recommended to the Board of
       Directors that the audited financial statements be included in the
       Company's Annual Report on Form 10-K for the last fiscal year for filing
       with the Securities and Exchange Commission.

     The Board of Directors has determined that the members of the Audit
Committee are independent as defined in Sections 303.01(B)(2)(a) and (3) of the
New York Stock Exchange's listing standards. The Board of Directors and the
Audit Committee adopted a written charter of the Audit Committee in 2000, which
they revised in 2001. The amended and restated Audit Committee charter was
included as Appendix A to the Company's proxy statement dated December 5, 2001
for the 2002 annual meeting of shareholders.

     During the fiscal year ended August 31, 2002, the Company paid the
following fees to Arthur Andersen LLP, the Company's principal accountants until
June 24, 2002: Audit Fees -- $65,755; Financial Information Systems Design and
Implementation Fees -- $2,660,595; All Other Fees -- $155,000. In addition, the
Company was billed the following fees by Ernst & Young LLP, the Company's
principal accountants since June 24, 2002: Audit Fees -- $210,000; All Other
Fees -- $12,000.

     The Audit Committee has considered whether the provision of the non-audit
services above is compatible with maintaining the auditor's independence and
concluded that it is.

                                          Members of the Audit Committee:

                                          Phillip L. Cohen (Chairman)
                                          Albert Cohen
                                          Donald J. Evans

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     During the 2002 fiscal year, the Company paid consulting fees of
approximately $27,000 to Anthony F. DiFillippo, a Director of the Company. Mr.
DiFillippo assists the Company in connection with certain employee matters.

     The Company retained during the 2002 fiscal year, and proposes to retain
during the 2003 fiscal year, the law firm of Goodwin Procter LLP. Donald J.
Evans, a Director of the Company, was formerly a partner of the

                                        13


law firm of Goodwin Procter LLP. Raymond C. Zemlin, the Secretary and Clerk of
the Company, is the sole shareholder of Raymond C. Zemlin, P.C., which is a
partner in the law firm of Goodwin Procter LLP.

DIRECTOR COMPENSATION

     Each Director who is not an employee of the Company receives a director's
fee of $10,000 per year, $1,375 per directors' meeting attended and $250 per
directors' meeting and committee meeting attended by telephone. A Director who
is also an employee of the Company receives no director's fees.

                                2. OTHER MATTERS

     Management is not aware of any other matters which may come before the
Annual Meeting; however, if any matters other than those set forth in the
attached Notice of Annual Meeting should be properly presented at the Annual
Meeting, the persons named in the enclosed proxy intend to take such action as
will be, in their discretion, consistent with the best interest of the Company.

INDEPENDENT PUBLIC ACCOUNTANTS

     The Board of Directors has selected the firm of Ernst & Young LLP ("Ernst
&Young"), independent public accountants, to serve as independent auditors for
the 2003 fiscal year. Ernst & Young has served as the Company's independent
auditors since June 24, 2002. A representative of Ernst & Young is expected to
be present at the Annual Meeting. He or she will have an opportunity to make a
statement, if he or she desires to do so, and will be available to respond to
appropriate questions.

     On June 24, 2002, the Board of Directors decided to no longer engage Arthur
Andersen LLP ("Arthur Andersen") as its independent auditors and instead engage
Ernst & Young to serve as the Company's independent auditors for the fiscal year
ending August 31, 2002. The decision by the Board of Directors to replace Arthur
Andersen with Ernst & Young was based on the recommendation of the Company's
Audit Committee.

     Arthur Andersen's audit reports on the Company's consolidated financial
statements for each of the years ended August 25, 2001 and August 26, 2000 did
not contain an adverse opinion or disclaimer of opinion, nor were they qualified
or modified as to uncertainty, audit scope or accounting principles.

     During the years ended August 25, 2001 and August 26, 2000 and through June
24, 2002, there were no disagreements with Arthur Andersen on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure which, if not resolved to Arthur Andersen's satisfaction,
would have caused them to make reference to the subject matter in connection
with their report on the Company's consolidated financial statements for such
years, and there were no reportable events as defined in Item 304(a)(1)(v) of
Regulation S-K.

     As reported in its Current Report on Form 8-K filed with the Securities and
Exchange Commission on June 27, 2002, the Company provided Arthur Andersen with
a copy of the foregoing disclosures. Attached as Exhibit 16 to that Current
Report on Form 8-K is a copy of Arthur Andersen's letter, dated June 26, 2002,
stating its agreement with such statements.

     During the years ended August 25, 2001 and August 26, 2000 and through June
24, 2002, the Company did not consult Ernst & Young with respect to the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's consolidated financial statements, or any other matters or
reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
