Workers at Parisian department store BHV were set to go on strike on Friday to protest against management and its deal with Shein which would give the fast-fashion retailer a permanent space on the seventh floor.

BHV owner Société des Grands Magasins has faced a wave of criticism in France, including from the mayor of Paris, since last week’s announcement of its partnership with Shein, which sends cheap clothes straight from factories in China to shoppers in more than 160 countries.

Shein, founded in China in 2012, has grown rapidly to become the world’s biggest fast-fashion retailer. It has been criticised by politicians, regulators, and other retailers over working conditions at its factories, high carbon emissions, and a lack of public information about its management and finances.

Hit by fines of 191 million euros in total from French and Italian regulators since July, the company is trying to tighten its internal controls to better comply with rules and improve its reputation with consumers. The strike was set for 3 p.m. local time, starting around the corner from BHV, according to a flyer featuring the logos of five different unions. The flyer said Shein’s launch at the department store would hurt BHV’s image and those of French brands.

SGM did not immediately reply to a request for comment. It said last week that the Shein store would attract younger shoppers and was part of its plan to modernise. Shein spokesperson Quentin Ruffat said the planned store would help increase the number of visitors to BHV and benefit other retailers.
