What are the rules on final paychecks in Illinois?

Generally, under 820 Ill. Comp. Stat. 115/5, an employer must issue a final paycheck to a terminated employee at the time of termination, or, if that is not possible, on the next regularly scheduled pay date. Likewise, an employee who quits his or her job is entitled to a final paycheck immediately, or, no later than the next regularly scheduled pay date.
