Industrial action has been suspended pending a ballot of members on the retailer's offer to improve redundancy and co-operation during closure packages.
Almost 300 drivers and warehouse staff took part in a one-day strike last Friday over the frozen food retailer's plans to close the distribution centre. A work-to-rule policy followed the strike and union members were threatening a full strike again today (Friday 21 July).
A T&G spokesman said: 'The members are being balloted on those proposals knowing an acceptance will mean the fight is over and notice periods will be worked. Equally, they are aware a rejection will mean strike action will be escalated to continuous strike action.'
Iceland chief executive Malcolm Walker said the decision had been taken to close the depot because it is the least efficient and most expensive.
If the closure goes ahead nearly all of the 300 employees will be offered the opportunity to relocate to a distribution centre in Warrington.
