A crisis at Cammell Laird shipyard has been averted after an agreement was reached with the company.
Hundreds of workers were balloted for strike action after several of their colleagues were suspended.
Trouble began when members of the RMT union - who were on strike in a separate dispute - picketed the gates of Cammell Laird.
Several workers, members of both GMB and Unite, stopped to talk to the picketers and were accused by the company of joining the picket and immediately suspended.
The company has now agreed to bring the suspended workers back to work immediately with no case to answer.
Albe McGuigan, GMB Organiser, said:
“GMB members showed great spirit and determination by moving forward with an industrial action ballot in support of their suspended colleagues.
“Workers were unnecessarily suspended after RMT staged a picket at the Birkenhead shipyard.
“Now, thanks to the support of their colleagues, these workers can get back to their jobs.”
