Workers at the Amazon warehouse in Coventry will walk out for seven further days in an escalation of a dispute over pay, their trade union said on Monday.
Last month GMB union members at the warehouse staged the first ever strike at the US e-commerce giant's operations in Britain.
GMB said more than 350 staff at Coventry warehouse would now take further industrial action on Feb. 28, March 2 and March 13-17.
"Amazon bosses can stop this industrial action by doing the right thing and negotiating a proper pay rise with workers," GMB senior organiser Amanda Gearing said in the statement.
Amazon, which employs 75,000 people across the UK, did not immediately respond to request for a comment.
It has previously said it already offers competitive pay and comprehensive benefits.
The company increased starting pay by 50 pence to a minimum of between £10.50 and £11.45 per hour last year, compared with a government mandated National Living Wage which will rise to £10.42 an hour from April.
GMB has said the Amazon Coventry workers are demanding £15 an hour, to help cope with surging inflation and a cost-of-living crisis which has sparked strikes across a range of different sectors in Britain over the last few months.
