(Harrisburg) -- The Turnpike Commission says the employee walkout in 2004 that forced it to collect a flat toll fee from motorists for a week isn’t likely to occur this month as employees negotiate a new contract. The Commission is in talks with more than 1,500 Teamster union workers, whose deal is up at the end of the month. Spokesman Carl DeFebo says both sides want to reach an agreement. "Teamsters union has been in place at the Turnpike Commission for more than 40 years and we’ve got a close working relationship and only once in that time has there been a road bump, if you will," he says. The union members are toll fare collectors and maintenance workers. DeFebo says he doesn’t anticipate a walkout, but if it does happen, the Turnpike will use non-union workers and collect flat fees from motorists. The last time union members went on strike, it was after they had worked on an expired contract for a year.
