A group of workers at the Civil Aviation Authority have escalated a pay dispute by taking a further two days of strike action from today (Tuesday).
The Public and Commercial Services (PCS) union members based at Gatwick and Canary Wharf previously walked out in January.
They are angry at a pay offer of just 3% for some staff.
PCS general secretary Fran Heathcote said: “Our members are proud to work for the CAA, keeping our airspace safe, but pride doesn’t pay the bills.
“They deserve to be treated fairly and paid fairly. Until they are, we’ve been left with little option but to escalate this dispute.”
A CAA spokesperson said: “We continue to engage with our union colleagues, and after prolonged discussions, it is disappointing that some Prospect and PCS union members are taking industrial action.
“Union membership makes up around one in five of our employees and we do not anticipate any disruption to the aviation sector, or any impact on our regulatory oversight activities or other safety critical work, as a result of this action.”
