Two more days of strike action are set to take place at the logistics operation of retail group Arcadia next week.
Workers at Spectrum in Leeds and Solihull plan to walk out on February 24 and February 26 over a Living Wage dispute.
Trade union GMB said its members balloted for strike action after their pay claim for a Real Living Wage – currently set at £8.45 by the Living Wage Foundation – fell on deaf ears.
Spectrum staff also walked out of the depot in Shirley on Cyber Monday – one of the busiest days of the year for online sales.
David Warwick, GMB organiser, said: “Not content with offloading BHS with a £571million pension black hole, Sir Philip Green now thinks it’s OK to leave his hard-working staff without a wage they can live on.
“Previous strikes at the Solihull site haven’t got the message home – now Leeds have joined in.
“How much more disruption is he happy to inflict on his customers before he does the decent thing and pays his dedicated long-standing staff properly?”
