Around 1,000 rail engineering workers in the RMT transport union at the contractor Jarvis took industrial action on Tuesday of this week against job cuts.
Jarvis is one of Network Rail’s key contractors. It plans to cut 450 jobs.
Workers refused to carry out overtime for all shifts and struck for an hour between 12 noon and 1pm.
The RMT held a national day of action at the same time, with rail workers and supporters protesting at parliament.
They demanded an end to cuts in rail jobs and services, a green stimulus for the railways and a people’s railway.
Workers at five other Network Rail contractors are also balloting for action over job cuts.
The RMT union suspended strike action at East Midlands Trains set for Friday of last week and agreed to talks brokered by the Advisory, Conciliation and Arbitration Service (Acas).
Almost 700 members were to strike over around 200 proposed job losses and the threat of compulsory redundancies.
Around 150 members of the Transport Salaried Staffs’ Association at CrossCountry Trains are reballoting for industrial action after management used anti-union laws against their first ballot over job losses.
The workers at the Birmingham-based firm are voting over 25 compulsory redundancies. They are also protesting against the sacking of a young manager who downloaded a union application form at work, where his personal emails had been monitored by management.
The ballot ends on 2 June.
Around 100 train conductors in the RMT union working at
London Midland depots at Bletchley, Northampton and Watford are continuing to strike every Sunday until 21 June against management’s plans to force them to work Sundays.
