SAN FRANCISCO (CBS/AP) — San Francisco’s public transit agency has reached a tentative deal with its operators on a new contract.

The new Municipal Transportation Agency contract would freeze wages. According to Muni management, it would also require drivers to work 40 hours a week or eight hours a day before qualifying for overtime.

Muni officials say the deal would save the city at least $21 million over the next three years. It still requires ratification by members of the Transport Workers Union Local 250-A.

A vote is scheduled for June 8.

The union’s executive board is calling for ratification. Union leaders said current employees would still not have to pay into their pension funds. The proposed contract would also eliminate a policy requiring operators to present a doctor’s note every time they call in sick.
