The largest union of PECO workers is set to announce its members are going on strike, which is the first work stoppage in PECO's history
Members of IBEW Local 614 have been without a contract since April 1 and are expected to announce a strike Thursday morning, because they say their demands are not being taken seriously.
Workers want better pay and improved retirement benefits.
PECO has previously said the utility is prepared to handle a strike and ratepayers do not need to worry about a work stoppage disrupting service.
