STAFF at the Wilko distribution centre in Magor could go on strike over the company's decision to bring in standardised seven-day working rotas.

A ballot held by the GMB union found more than 90 per cent of workers at two Wilko warehouses – in Magor and in Worksop, Nottinghamshire – would take industrial action over rota changes which would include compulsory weekend shifts.

A Wilko spokesman said the new rotas would align with the shopping needs of its customers, who were described as "hard-working families that shop 7-days a week".

He added: "For several years now, team members in our distribution centres have worked weekends in response to customer need.

"This is already part of their existing contract of employment and our current discussions are about making this a more regular working pattern."

But Gary Carter, GMB national officer, described the new rotas as "brutal", saying: “More than 90 per cent of our members are so angry they are willing to walk out – that shows the strength of feeling amongst staff."

Mr Carter added: "Wilko bosses have given no consideration to work/life balance. Many people need consecutive rest days and time with their families.

“To cut this off will have implications for their health and wellbeing, their safety and their family lives.

"People feel they’re being forced out of the job after many years of loyal service."

More than 2,000 people work across the Magor and Worksop sites, which supply Wilko stores across the UK

GMB said talks had been held after Easter to avert the dispute, but had broken down after management failed to compromise.

The union went on to say it would be conducting a full strike action ballot because the strength of feeling amongst the workforce was so strong.

The Wilko spokesman said: “We are incredibly disappointed to hear the GMB talk about taking a more disruptive course of action.

"We understand this topic is as important to our team members as it is to our customers.

"We are continuing to talk to our team members and their representatives about creating rotas which meet the needs of our customers while enabling a work/life balance.”

But Mr Carter said many staff felt like going on strike was the only remaining course of action.

“We’ve offered several alternatives to these enforced rota changes, but management don’t seem to be listening," Mr Carter said.

“Members now feel they have no option but to take part in a strike ballot.”
