Alitalia faces a strike by cabin crew at the end of the month after being asked to tidy more aircraft toilets.
Staff at the loss-making Italian carrier plan to walk out on February 23.
They are protesting against a raft of cost-cutting measures, including being made to tidy the bathrooms, and replenish soap and toilet paper on long-haul flights.
Cabin crew are already expected to look after the bathrooms on short-haul flights, but are now being asked to extend that duty to long-haul services.
An Alitalia spokesman told the Daily Telegraph that cabin crew were not being asked to clean toilets but only “refill” the bathrooms, with “soap, towels, etc.”
The airline is also asking unions to accept a pay cut, as well as a reduction in summer holiday and annual leave, requests the unions have called “inadmissible”
