Birmingham Airport could be the latest to be hit by strikes this summer if workers who've faced real-term pay cuts for two years walk out.
The West Midlands travel hub is facing potential chaos if 100 security officers, terminal technicians and aircraft refuelers employed by Menzies go ahead with plans to walk out.
The workers are due to be balloted over pay, with the majority of those surveyed being security officers who have "unsociable" shift patterns, earning around £11.50, according to Unite.
