Ground handlers, passenger assistance and other airport workers at Gatwick have been negotiating with various employers including Red Handling, Wilson James, Menzies and ASC, in separate pay disputes.

Last month some planned strikes were called off after workers received improved pay offers. However on Wednesday Unite said workers from Red Handling and Wilson James would take industrial action.

The latest strikes, which will take place in various tranches from Aug. 18-28, ending on the day of a national bank holiday in Britain, will disrupt or delay over 200 flights during the first four days, Unite said.

"Red Handling and Wilson James need to wake up and smell the coffee, other employers at the airport are prepared to pay the going rate and there is no excuse why they shouldn't do the same," Unite general secretary Sharon Graham said.

"There is no way our members will accept a real terms pay cut and poverty pay."

Hundreds of thousands of workers in Britain have been taking strike action since last year as pay rises fail to keep up with high inflation.

Gatwick airport did not immediately respond to a request for comment.
