disruption, the strike was called off by local union officials. In May 1970, the teachers again authorized a strike over salary. While negotiations continued throughout 1970 and into 1971, the authorization to strike was reaffirmed in March 1971. The strike threat continued into the 1971–72 school year. Teachers again authorized a strike in September 1973 over payment for non-teaching time. Teachers did follow through with their strike threat despite an offer of 8% increase in salary. After five days, teachers accepted a contract with an 8% pay increase in the first year, and a gradually increasing pay increase throughout the life of the three-year contract. In September 1976, the teachers union again authorized a strike, this time at the cost of seven days of school. When the strike took place, teachers were threatened with firing, which a judge requested the school board delay. This strike ended after seven days. 1979 saw another strike, though classes were able to resume on a modified schedule with teachers who crossed the picket line and substitutes. After 15 days, the strike was ended with double-digit salary increases for teachers. A 1985 strike lasting 11 days ended after the teachers and Board of Education submitted to an arbitrator to solve final details of the contract. The remainder of the 1980s and early 1990s remained relatively quiet. 1996 saw the next strike action. The Board of Education tried to force teachers back to work, claiming the strike was illegal during arbitration sessions, though teachers remained on strike. As the strike wore on, some of the fall sports teams were forced to forfeit their final regular season games and their state playoff games. The situation worsened when it was learned that the federal mediator had taken a week off to attend a conference at a resort. The Illinois Labor Relations Board publicly condemned both sides for failing to work in earnest to end the strike. By November 2, the District began announcing plans to replace striking teachers by as early as November 18. Parental involvement eventually helped end the strike on November 4 after 14 days. The final contract was ratified in January 1997, with the district stating an estimated cost of the strike at US$300,000, including a need to sweep areas for electronic eavesdropping devices.
