Bargaining negotiations between the Issaquah School District and Teamsters Local 763 have continued with a fourth mediation session Dec. 3, where the district provided the Teamsters with a package proposal consisting of economic enhancements and non-economic proposals, according to school district officials.

A representative from Teamsters Local 763, representing custodial and grounds maintenance workers, filed charges with the state’s Public Employment Relations Commission Oct. 17, citing claims the district is not negotiating contracts in good faith.

A representative from the International Association of Machinists, representing bus mechanics, filed similar charges Oct. 28.

Much of the disagreement between the unions and the district centers on language disputes, cost of living adjustments and health benefits.

The newest district proposal consists of a three year contract with an economic package providing for a .5 percent increase above the 4.4 percent cost of living allowance, according to district officials.

Other aspects of the proposal:

– Affected workers will be compensated at 97 percent of their higher wage rate for the first two years of service, then receive a higher rate of pay in their third year.

– An increase in the attendance incentive: an $800 bonus for those who miss a maximum of two work days in a year, and a $400 bonus for a maximum of four missed days.

– Another .5 percent increase above the cost of living allowance in year two, and a 1 percent increase in year three.

The district is currently attempting to secure more mediation dates.

After charges were filed in October, commission investigators reviewed the charges and determined extra bargaining sessions were required.

Contract negotiations have been ongoing, and grew tense between the district and the unions in spring, officials said.
