Two thirds of GMB members at the Washington distribution centre voted to take strike action from Wednesday, July 27 after rejecting Asda’s pay offer. Some 400 staff will now walk out.
GMB organiser Mark Wilson said: “GMB members have clearly demonstrated that they are not satisfied with what the company has offered by the level of the vote for strike action.
“My advice to the company is to get back to the negotiation table and sort out a deal with the members.”
However an Asda spokesman said it understood that only a third of the workforce had voted in favour of the strike action and said that the pay deal of 7.75% over two years, back-dated to January, was a great offer.
“We're disappointed, but we've already put contingency plans in place - customers won't notice a thing.”
Meanwhile, Morrisons still faces the threat of an all out strike at its distribution centres over pay talks.
