Over 500 Amazon workers at the company’s main distribution hub in Italy are planning to go on strike on Black Friday, reports Reuters. Italian trade unions said the workers from Amazon’s Piacenza hub in northern Italy had agreed to strike for the first time after they failed to negotiate bonuses with Amazon. The workers also want pay raises to compensate for mandatory night shifts, overtime, or working six days in a row to keep up with logistical demands.

Additionally, starting from Black Friday, the striking workers will refuse overtime during the holiday season — typically the busiest season for the company — until December 31st.
