Holidaymakers have been warned of the potential for strike action at Glasgow Airport over the summer as more than 800 workers from five companies are involved in pay disputes.
Unite the union said workers at Glasgow Airport Ltd, ICTS Central Search, Swissport, Menzies Aviation and Falck could be balloted for walkouts.
The union said on Saturday that if there is no successful resolution to the disputes in the coming days, it will move towards holding votes on industrial action within two weeks.
