YONKERS - Some school bus workers in Westchester hit the picket line this morning after they say they were told not to come to work.

About two dozen mechanics protested, saying that they were not being treated fairly by Mile Square Bus Transportation on Nepperhan Avenue in Yonkers. Their union, Local 100, believes the lost hours are retribution after workers went to OSHA complaining of bone-chilling temperatures in the break rooms and restrooms. The union’s vice president says cutting mechanics means cutting safety on school buses.

"At this moment, the buses are out on the road with no mechanic to fix what defects they may or may not have," says Local 100 Vice President Angel Giboyeaux.

Representatives from Mile Square Bus Transportation counter those claims and say the cut hours are a result of potential fines that could come after OSHA's investigation. He says the union is looking for trouble.

"I think there is something else. All this is just a plan to hurt the company," says Mile Square Bus Transportation's Harry Rodriguez.

Officials tell News 12 that OSHA did visit the site, but has not yet concluded its investigation.

Westchester union representatives say a deal was reached Tuesday afternoon, and mechanics were back at work by the end of the day.
