DES MOINES, Iowa (AP) — A state official says about 30 union locals will dismantle following elections required by Iowa’s new collective bargaining law. Mike Cormack, chairman of the Public Employment Relations Board, based his estimate Wednesday on preliminary results from recertification elections held over two weeks ending Tuesday. He says nearly 430 union units secured enough votes to continue, while 31 units did not. Almost 40 units remain to be counted, which means the tally can change.

More periodic recertification elections were required under a law approved this year by the Republican-majority Legislature that eliminated most collective bargaining rights for public workers.

Cormack says more than 28,400 employees voted, with more than 23,000 supporting retaining their unions and a little over 530 supporting decertification. Those who don’t participate are counted as “no” votes.
