Union officials at Spanish flag-carrier Iberia have warned they may call workers out on strike over Christmas in protest against job cuts at the airline.

Members of the UGT union, the second biggest in the country, are considering strike action between December 14th and 21st.

“All of the unions are in intense talks to fix dates for action against the plan to dismantle Iberia,” a spokesman for the group said.

Iberia is part of the International Airlines Group.

As part of an overhaul designed to return the airline to profitability, IAG said last month it would cut about a quarter of the Spanish airline’s workforce.

Cuts are also set to be made to capacity as part of a restructuring plan to make it more competitive.
