It is believed that Sligo workers will strike again on Friday, 14 December.
Tesco staff in Carrick-on-Shannon, have reportedly voted in favour of industrial action also workers will reportedly strike on Saturday, 22 December.
Earlier this week Tesco has issued a statement to call on Mandate to call off its one-day strike threats in two stores.
"If Mandate proceeds with the proposed unwarranted one-day strike actions for the two stores, both will continue to remain open to serve customers," the UK retailer said in the statement.
We regret that Mandate is inflicting this inconvenience on our customers in December when our stores are at their busiest and particularly given these stores are close to the Border."
