Mandate serve strike notice after 99% vote in favour
Around 1,000 Tesco employees have voted in favour of industrial action over plans to reduce their pay and conditions.
Mandate trade union, which represents workers in Tesco Ireland, balloted their members on strike action.
The ballot included an 85% turnout - and 99% of those voted to back the move.
Brendan O'Hanlon from the Mandate Trade Union said that strike notice would be served on the company, but "will only take effect if the company cuts the workers' wages".
"It's overwhelmingly in favour, and unsurprisingly so given the extent of the changes," he added.
Earlier, the supermarket multinational said it was deferring its plan to reduce pay and conditions by between 15% and 35% for around 1,000 of its 14,000 employees until Monday 16th May.
It has also opened a voluntary redundancy scheme for staff.
The dispute centres on around 1,000 workers, 6% of the Tesco workforce, who hold pre-1996 contracts of employment involving better pay and conditions than those recruited since.
Tesco argue that these older contracts are not sufficient to meet the needs for longer opening hours and changed trading patterns in the intervening decades.
The pre-1996 workers are employed in 89 of the company's 149 stores.
