Virgin does not recognise the PPU, which represents around 450 of its 800 pilots, and chooses to negotiate instead with the British Airline Pilots Association, or Balpa.
Outgoing Virgin Atlantic chief executive Craig Kreeger wrote to pilots last week to explain changes to the terms and conditions of their employment, the Financial Times reports.
These changes include capping income protection, cancelling a dependants’ pension scheme, and reducing corporate pension contributions.
The PPU in a statement issued on Thursday (November 8) branded the move a “cost-cutting exercise”.
