Hundreds of G4S security staff who deliver cash and coins have voted to strike in December, prompting fears of shortages ahead of Christmas.
The industrial action could impact the supply of cash and coins at banking clients such as Barclays, HSBC and Santander, and supermarkets including Tesco, Asda and Aldi. The GMB union said it will be the first ever strike at G4S after union members voted to walk out, with a 97% vote in favour of action.
It said the strike is scheduled to take place from 3am on December 5. The security operator and outsourcing firm said it has "contingency plans" to mitigate disruption if the strike goes ahead.
