Thousands of workers at high street chain Wilko have voted to strike in adispute over a new rota system.
Around 1,600 GMB members at two distribution centres including Worksop, Nottinghamshire, will walk out, saying they are being forced to work weekends.
The union has not yet announced the dates of industrial action.
GMB official Nicola Savage said: "More than 84% of votes were cast for strike action. It's clear how angry workers are about this brutal new rota system.
"Wilko prides itself on being a family run company, but they're imposingcontracts that will force staff to work on the weekends, splitting up familytime, without the agreement of their employees.
"Our members feel backed into a corner, and strike action is the only optionleft open to them."
A spokesperson from Wilko said:
We share our team members frustrations and we remain committed to working with them and their representatives to further reduce the number of weekends they need to work, so that they can spend as much time as possible with their families.
