The Balearic Islands branch of the CCOO Habitat Federation has filed a complaint with the Labor Inspectorate regarding the alleged non-payment of wages and excessive working hours of its employees at a subcontracted company working on the renovation of both Palma Airport and Manacor Hospital. The union, in a statement outlining the events as reported by the workers themselves, also highlights alleged falsification of daily reports, cash payments without social security contributions, employees being denied vacation time, per diems "disguised and misappropriated" as advances, and transfers to the Spanish mainland without prior agreement. According to the union, as of Wednesday, the workers had still not received their wages and were working ten-hour shifts despite signing documents purporting to show they were only working eight.

Workers from different sectors have mobilized in recent months to demand fair working conditions. Those from the TIB (Spanish Institute of Industrial Property) called an indefinite strike, which ended on Friday, after reaching an agreement with the intercity transport concessionaires in Mallorca. Subcontracted ground service workers at Palma Airport threatened to "cause a total collapse" in August if their situation did not improve. Teachers at Palma's outsourced daycare centers also went on strike in April to demand equal pay with the rest of the municipally managed centers. These three examples share a common and significant feature: they involve bidding by public administrations to offer services through private companies.
