A three-week strike by Cardiff Bus workers - due to begin next weekend - has been called off.
450 staff, including drivers, were due to stage a walkout between 17th August and 7th September in a dispute over pay and conditions.
But the Unite union has suspended industrial action and will ballot its members on an improved pay offer.
Craig Hampton-Stone, Cardiff Bus managing director, said: "We were pleased to hear of the suspension of the planned industrial action from Sunday to allow for another workplace ballot to be undertaken."
"I would urge all taking part in the ballot to accept the latest revised offer."
Unite regional secretary Peter Hughes said: "Cardiff Bus has returned to negotiations and put an improved offer on the table. Unite has therefore suspended strike action to allow members to be balloted on the proposals."
Unite members had previously rejected an offer from the company which, according to a spokesperson "left driver pay below levels in the rest of the UK, while timetabling issues had left workers unable to take proper breaks and workers also had unsatisfactory sickness terms."
Last week, Cardiff Bus said it offered further unconditional improvements to its original offer, including a 5.86% increase across all rates of pay, longer breaks and improvements to their sick pay scheme.
Unite confirmed that all strike dates are currently on hold, pending the outcome of the ballot, which will run for two weeks from Friday.
