Mayor of Bratislava Matus Vallo is due to meet representatives of city public transport drivers on Tuesday in order to avert a possible strike, said Bratislava city authority spokesman Peter Bubla on Monday. Two trade unions representing public transport drivers in Bratislava announced a strike alert as of May 1, while issuing a deadline for Bratislava Public Transport Company (DPB) to reach a deal on salary hikes by May 9, or they'd "consider announcing a strike".
