The RMT said its rail signalling staff at the West of Scotland Signalling Centre will be striking again for 24 hours.
The union said the two strikes have been called ‘following a total failure by the management to make any progress’ regarding a dispute over career progression.
The RMT said strikes will take place on Tuesday 14th February and Friday 2nd March 2012.
RMT General Secretary Bob Crow said:
“RMT has tried to reach a negotiated settlement to this unilateral ripping-up of a local arrangement but unfortunately the management have refused to see sense and have failed to engage with us at all since the strike action over Christmas.
“RMT members will not stand by while management unilaterally rip-up agreements and practices that have been in place at local level for decades.
“As a consequence of management’s continued intransigence we have no option but to go ahead with this further wave of strike action.”
