Topshop owner Sir Philip Green may be in for a turbulent Christmas after the chain's supply chain workers in the UK voted for fresh industrial action. 

Workers at Spectrum, the distribution arm of Arcadia Group, have been locked in a battle over salaries and contracts. Most employees at the Solihull depot are paid GBP7.20 an hour, the minimum wage for over-25s. However, the GMB union says workers want the independently-calculated living wage of GBP8.45.

"The way we have been treated by Arcadia is utterly shabby," says Dominic Hinks, GMB organiser. "On the ground, the company's reps have been very good – but we are getting nothing from head office. We have even offered up counter proposals – but all we get in return is silence. Now we have no choice but to take further action."

Over half of the 200 staff threatened to walk out today (8 December) and again on Monday. The move follows a strike that took place on Cyber Monday (28 November), one of the busiest trading days of the year.

The GMB says the walkout is likely to throw festive deliveries into chaos from Arcadia's brands such as Topshop, Miss Selfridge and Burton men's wear.

The union says Arcadia has made no effort to contact workers.

Green recently faced calls from MPs to seize his GBP100m luxury yacht to plug a pension black hole at his former company, department store group BHS, which he sold for GBP1 in March last year.

BHS went into administration in April this year, and in June the administrators announced plans to liquidate the BHS UK business, after more than eight decades of trading and with the loss of up to 11,000 jobs. The retail chain's final stores closed down in August.
