Illinois: New-Hire Wage Notice Requirements

Requirements one by one

Written notice at hiring

The statute requires notice at hiring of the rate of pay and the time and place
of payment. Its “whenever possible” wording is not a general permission to use
an unwritten arrangement. The rule (§ 300.630(d)) requires the rate notice in
writing, and § 300.630(e) puts the burden on the employer to show that a
written notice of the rate and payment time/place was not possible.

The Act covers Illinois employers and employees, including local-government
and school-district employees, but excludes State and federal employees.

The rate description reaches each compensation component

The rule says “rate of pay” includes a description of all wages or final
compensation. Its definition of compensation lists hourly wages, overtime
wages, commissions, piece-rate work, salary, bonuses, expense reimbursements,
and any other basis used to calculate pay for services.

That makes a single annual-salary or hourly-rate line incomplete when another
compensation component applies. It does not turn unrelated benefit-plan terms
or planned deductions into required hire-notice fields.

Changes must be prospective and documented

An employer must notify the employee before a pay arrangement changes. The
rule calls for the change to be put in writing and presented at the time of the
change. If extraordinary circumstances make immediate writing impossible, the
employer must rectify that immediately.

Continued work after written notice creates a presumption of assent, absent
contrary evidence. Continued work without advance written notice does not show
consent to an adverse modification, and the employer may not retroactively
reduce wages already earned.

Copies of the required hire and change notices belong in the employer's
three-year records under § 300.630(a). That is a notice-copy rule, separate
from the Act's pay-stub retention requirements.

Enforcement

The Illinois Department of Labor enforces the Act. Section 115/11 also permits
an employee aggrieved by an Act or rule violation to sue without first
exhausting the administrative route.

For an Act violation not covered by the unpaid-wage, order-enforcement, or
retaliation remedies, § 115/14(d) authorizes a civil penalty of up to $500 per
violation payable to the Department. The Act does not assign that penalty to
the employee or state a separate notice-only damages formula.

What trips people up

The poster does not replace the individual notice. Section 115/10(e)
separately requires a workplace posting showing regular paydays and the place
and time of payment. Section 115/10(a) and the rule still require the employee's
own hire notice.

“Whenever possible” has a burden attached. The employer, not the employee,
must show why written notice was impossible. The rule also requires an
impossible-to-write change to be documented immediately afterward.

Starting work is not blanket consent to later reductions. Commencing work
reflects mutual assent to the initial rate. A later adverse change still needs
written notice before its effective date.

Common questions

Can an offer letter satisfy the Illinois notice rule?

Yes, if it is delivered at hiring and states the payment time and place plus a
description of every applicable wage or compensation component. It also must
be handled as a required notice for acknowledgment and three-year retention.

Must an applicable overtime component be described?

Yes. The administrative rule defines compensation to include overtime wages,
and the rate-of-pay notice must describe all wages or final compensation.

May an employer reduce the rate for work already performed?

No. Section 300.630(d) bars an employer from retroactively adversely affecting
wages already earned.
