Virgin is still not a happy place for all and a lot of issues with management.
Flight deck continue to leave every month from both Boeing and Airbus fleets for better employers.
The recent union agreement did not stop people leaving as what was hoped by the company. Some resigning recently upon finishing line training to join BA. The staff travel is not good but the pension is good with the company contribution level.
Those leaving have been joining BA, EK, Jet2 EZY and DHL etc. It's expected to continue during 2025 and the company is sponsoring non UK citizens for visa's and supporting license conversations.
As mentioned in another post, it would be better joining BA or one of the other above mentioned airlines.
