City bus drivers received noticed this month that the management company that runs Racine's Belle Urban System didn't make the drivers' pension and health insurance payments in December and January.
Professional Transit Management, the company hired by the city to run the BUS, is about $90,000 behind on its payments. It also hasn't made the February payment, according to a source close to the drivers.
The drivers are members of Teamsters Local 43.
The source said Central States Funds, which manages the drivers' benefits, set a March 14 deadline to make payments or it will discontinue benefits.
Bus drivers said it appears to be an oversight, but they were unclear who was responsible or when it would be fixed.
RacinePost couldn't reach union and PTM officials for comment.
City Administrator Tom Friedel referred comment to PTM, which manages all aspects of the city's bus systems.
The city budgeted to spend about $9.1 million on its bus system this year.
The bus drivers and PTM had a contentious relationship last year over a new contract. The drivers briefly went on strike in May before settling a contract with PTM.
