115 ILCS 5/15
A charge of unfair labor practice may be filed with the Board by an employer, an individual or a labor organization. If the Board after investigation finds that the charge states an issue of law or fact, it shall issue and cause to be served upon the party complained of a complaint which fully states the charges and thereupon hold a hearing on the charges, giving at least 5 days' notice to the parties. At hearing, the charging party may also present evidence in support of the charges and the party charged may file an answer to the charges, appear in person or by attorney, and present evidence in defense against the charges.
The Board has the power to issue subpoenas and administer oaths. If any party wilfully fails or neglects to appear or testify or to produce books, papers and records pursuant to subpoena issued by the Board, the Board shall apply to the circuit court for an order to compel the attendance of the party at the hearing to testify or produce requested documents.
If the Board finds that the party charged has committed an unfair labor practice, it shall make findings of fact and is empowered to issue an order requiring the party charged to stop the unfair practice, and may take additional affirmative action, including requiring the party to make reports from time to time showing the extent to which he or she has complied with the order. No order shall be issued upon an unfair practice occurring more than 6 months before the filing of the charge alleging the unfair labor practice. If the Board awards back pay, it shall also award interest at the rate of 7% per annum. If the Board finds that the party charged has not committed any unfair labor practice, findings of fact shall be made and an order issued dismissing the charges.
The Board may petition the circuit court of the county in which the unfair labor practice in question occurred or where the party charged with the unfair labor practice resides or transacts business to enforce an order and for other relief which may include, but is not limited to, injunctions. The Board's order may in its discretion also include an appropriate sanction, based on the Board's rules and regulations, and the sanction may include an order to pay the other party or parties' reasonable expenses including costs and reasonable attorney's fee, if the other party has made allegations or denials without reasonable cause and found to be untrue or has engaged in frivolous litigation for the purpose of delay or needless increase in the cost of litigation; the State of Illinois or any agency thereof shall be subject to the provisions of this sentence in the same manner as any other party.
