Signalling staff in Wales and the Marches area are striking for six days this week against the imposition of rosters at the South Wales Control Centre.
Network Rail wants to impose an eight-hour roster over the existing 12-hour one.
The RMT transport union members were striking from Monday to Saturday, and they were to begin a four-week overtime ban on Sunday.
This follows six hard-hitting days of strikes in December that hit the South Wales Control Centre, Newport panel, Vale of Glamorgan, Rhymney Valley, Cardiff panel and Port Talbot panel.
The RMT is also balloting for action in other areas.
The mood to escalate was clear on picket lines during the last strike – as was the bitterness at managers being drafted in to do workers’ jobs from around the country.
“We are more united now then we were at the start of strike,” one picket told Socialist Worker. “We’re not allowed to picket outside our area – but Network Rail have got managers coming in to do our work from round the country.”
Newport RMT branch secretary Steve Richards said, “We want other signal workers around the country to see the strike and think ‘we can do this too’.” The signal workers have received solidarity from signallers from Fort William and Derbyshire, and other trade unionists.
