Tesco has called on Mandate trade union to withdraw strike notices at two stores in Sligo and Carrick-on-Shannon.
Mandate members at the two stores in the North West voted overwhelmingly for industrial action.
However, in a statement the company says the action is unwarranted and the stores will remain open on the two days in December pencilled in for strike action.
They say they have always abided by agreed procedures and expect the union to do so.
The union today announced the action is scheduled for Thursday December 6th and Friday 14th over a number of issues.
Mandate's Ciaran Campbell says if necessary they will look for support from other stores.
