Nearly 1,000 Spanish speaking Amazon (NASDAQ: AMZN) workers have been called on to go on strike and walk out for three days next week, during Amazon’s Prime Day week, by Spanish labor unions to dispute efforts to reduce worker rights. The strike will be ongoing from July 16th to July 18th, which covers Amazon’s one and a half day sale for Prime members, at the San Fernando warehouse, where a majority of Amazon’s 1,600 Spanish employees work. This will mark the second walk-out strike that occurred this year at the San Fernando Warehouse.

The strike is an attempt to retaliate against wage cuts, working conditions, and restrictions on time off, Douglas Harper, a representative of the Comisiones Obreras union, told Reuters. "Strikes aren't good for anyone, not the company, the workers or the customers, but we need to keep putting pressure on local management," Harper said.

The Company announced earlier in the month that it would hire 1,600 more employees on permanent contracts in Spain this year.

Amazon said in a statement that the Company’s total pay is “at the high end of the range in the logistics sector” and that they offer an “attractive salary and an extensive benefits package.”
