Strike action among National Express bus drivers in the West Midlands is back on - just days after it was called off following a revised pay offer.
Trade union Unite has claimed the Birmingham-based transport group has refused to allow staff to vote on that latest pay offer, something National Express disputes.
As a result, all-out indefinite strikes will commence on Monday, involving 3,100 drivers and impacting 93 per cent of the West Midlands' bus network.
