SUPERMARKET chain Morrisons faces the prospect of strike action at three depots supplying its stores.
Members of the Transport and General Workers' Union based at distribution centres in Wakefield, Cheshire and Bristol, have voted to go on strike over job cuts.
And the GMB general union was today balloting Morrisons' employees on strike action against the Bradford-based firm.
The TGWU said that industrial action raised the prospect of "serious shortages" on the shelves at Morrisons' supermarkets.
But Morrisons stressed it had 12 other depots where workers were not involved in the ballots.
Morrisons has stores at Waterloo and owns the former Safeway store at Meltham.
TGWU national officer Brian Revell accused the firm of refusing to consult with unions over jobs and said Morrisons had "blocked" trade union activity.
GMB spokesman Steve Pryle said: "If GMB members vote for strike action the unions will consider what form of industrial action will take place and on what date."
A spokeswoman for Morrisons said the strike votes affected three of its distribution centres, adding: "We have 12 other sites operated by third parties and represented by other trade unions not involved in these ballots."
She said Morrisons had told union officers the company was happy to discuss the ballot results.
