GENERAL INFORMATION

The enclosed proxy is being solicited on behalf of the Board of Directors
of UniFirst Corporation (the "Company") for use at the 2000 Annual Meeting of
Shareholders to be held on January 11, 2000 (the "Annual Meeting") and at any
adjournment thereof. This Proxy Statement, the enclosed proxy and the Company's
1999 Annual Report to Shareholders are being mailed to shareholders on or about
December 2, 1999. 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 19, 1999
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
9,408,134 shares of common stock, par value $.10 per share ("Common Stock"), and
10,255,744 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 2003 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 as a separate class, to serve as a Class I
Director and Aldo Croatti to be elected by holders of Common Stock and Class B
Common Stock, voting together as a single class, to serve as a Class I Director
(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 either of
the Nominees will be unable to serve as a Director, in the event either or both
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 as a separate 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
Aldo Croatti. 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 1999 fiscal year, the Company believes that, during
fiscal 1999, all officers, Directors and greater than 10% shareholders complied
with the applicable Section 16(a) filing requirements, except that Aldo Croatti
inadvertently failed to file a Form 4 for a transaction subsequently reported on
Form 5.

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 two 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). Additionally, the
designated beneficiary will receive a lump sum benefit equal to 40% of the
participant's Final Average Earnings. The SERP provides that, upon any change of
control, retirement benefits of participants who are age 50 or 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.

REPORT OF COMPENSATION COMMITTEE

The Compensation Committee currently consists of Albert Cohen and Donald J.
Evans, two Directors who are not employees of the Company, and Aldo Croatti,
Chairman. 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, in the beginning of fiscal 2000 the Company issued
options to purchase a total of 57,000 shares to over 90 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.

7
10

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 paid to
executives at other companies generally.

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. No bonuses were paid to executive officers for fiscal year 1999.

COMPENSATION OF CHIEF EXECUTIVE OFFICER

The Compensation Committee established the compensation of Ronald D.
Croatti, the Chief Executive Officer, for 1999 using the same criteria
applicable to determining compensation levels and bonuses for other executive
officers as noted in this report. Based on the financial performance of the
Company during the 1998 fiscal year, the compensation levels paid to executives
of other companies generally and Mr. Croatti's contribution to the
profitability, sales growth, return on equity and market share of the Company
during the 1998 fiscal year and his leadership of the Company, Mr. Croatti's
1999 calendar year base salary was established at $313,389, an increase of 4.5%
over the prior year.
