GMB said more than 560 workers at the warehouse would walk out on April 16-18 and April 21-23. Workers at the site staged the first strike at the U.S. tech company’s operations in Britain in January, followed by a further seven days in February and March.
“Six further days of strike action in Coventry is a clear statement from our members they are worth more; they will not accept a pay rise of pennies from one of the world’s wealthiest corporations,” Amanda Gearing, GMB Senior Organiser, said in a statement.
The union said on Friday it would also begin balloting workers at five fulfillment centres across central England for industrial action.
Amazon, which employs 75,000 people across the UK, did not immediately respond to Reuters’ request for a comment.
It has previously said it already offers competitive pay and comprehensive benefits.
