Iberia staff at pilots union SEPLA are to follow other workers at the Spanish airline in holding planned strike action next month.
The union qualified Iberia's announcement of making 3,807 redundancies following the announcement of strikes by unions representing its ground staff and cabin crew as "unacceptable."
SEPLA, which has been negotiating with Iberia's parent company International Airline Group separately from other unions, says the company has refused to negotiate any proposal submitted by the pilots.
The union says that in Iberia's restructuring plan, only 15 of the 400 senior executives are affected, with none in the management team. "Senior management staff will see their wages reduced by 20% compared with 40% average pay cut for the Iberia's staff," it says.
Iberia's ground staff and cabin crew unions have already called for 15 days industrial action scheduled for 18-22 February, 4-8 March and 18-22 March.
SEPLA will join the later strikes on 4-8 March and 18-22 March, but not the February stoppage as this comes too soon to meet minimum strike notice required under Spanish law.
