The union, Unite, says it is 'shocked and dismayed' at the announcement that Dunlop Motorsport will close its factory in Birmingham - causing a loss of at least 241 jobs.
On the plans to move their business to France and Germany, Unite says:
We are shocked and dismayed at the announcement made today of the closure of Dunlop Motorsports with the loss of 241 jobs.
Just four days ago they committed, at a meeting convened by business secretary, Vince Cable, with the support of Birmingham city council, to seriously investigate the possibility of relocation in the Birmingham area.
Unite will not accept the company walking away from its commitments or its obligations to fully consult the workforce on this decision and will be looking to challenge and change the decision.
