Preliminary agreements have been reached with CTU and SEIU Unions, CPS employees and the employees they represent are presented in the table below. Links to the current collective agreements between CPS and the unions are at the bottom of the page. The guidelines and rules of the CPS Board of Directors also affect the terms and conditions of employment of CPS employees. You will find Chapter 4 of the commission rules and the 500 series of boards of directors. Personnel procedures and other personnel materials are published on the internal CPS HR4U staff website. After the contract expired in June 2015, CPS teachers continued for one year without a contract, while the union and district negotiated. In September 2016, union members voted overwhelmingly in favour of the strike in the absence of an agreement and set a deadline until 11 October. A few minutes before midnight on October 10, the district and the union tentatively agreed and prevented a strike.  On September 14, 2012, teachers tentatively agreed with the city that preferences for teachers dismissed following a school closure at another school and student exam results were less favourable to teacher evaluation than the city had originally planned.  However, this interim agreement did not last and the strike continued, after which Mayor Emanuel announced his intention to seek an injunction and force teachers to return to work.  On September 17, 2012, Mayor Emanuel`s efforts to end the strike stopped when the second week was stopped.
 CTU delegates voted to end the strike on September 18, 2012.   Students began returning to school on Wednesday, September 19, 2012. The CTU still had to ratify the contract with the 29,000 teachers in the Union.  CTU intensified its campaign for collective rights in the 1960s and organized large demonstrations at the Chicago Board of Education.  Pressure came after New York recognized the tariffs of the FTU in 1961 and threatened the CTU with an illegal strike in 1963-64 if the school board did not grant it the same status.  The city prevented the strike by agreeing to negotiate and after long delays (including disputes by a rival union, the Chicago Education Association) , CTU became the official partner of Chicago teachers in April 1966.  Here you will find information on CPS tariff units, agreements and general information on CPS collective bargaining.
