Bus services in Leeds could be affected by strikes next month as union ballots for action
More than 650 bus workers are being balloted on whether to strike in a dispute over pay.
Members of Unite employed by Arriva in Yorkshire will vote in the next few weeks on whether to launch a campaign of industrial action.
The union said the dispute was over a pay offer of 4.1 per cent, which it pointed out was less than half of the current RPI inflation rate.
Arriva runs 10 bus routes in Leeds, including the 110 to Hall Green, the 163/166 to Castleford, the 200/201 to Heckmondwike and the 202/203 to Huddersfield.
Workers being balloted include bus drivers and engineers, based at depots in Castleford, Dewsbury, Heckmondwike, Selby and Wakefield.
Unite said many of the bus drivers were struggling to make ends meet because of the cost-of-living crisis.
The ballot will close on May 23, so strikes could begin in early June if there is a yes vote.
Unite general secretary Sharon Graham said: "This offer is a pay cut and is unacceptable to Unite. Arriva has to think again and come back with an offer that fully reflects this cost-of-living crisis."
