They are making FD redundant so I would be surprised if they are not doing the same for the crew.
The difference is that crew historically joined almost weekly, courses through training college were running like a sausage machine. Unlike FD, crew are on 3 year contracts and as such there are crew reaching the end of their 3 year contract at the same pace as they joined. That is convenient for the company since they dont need to make them redundant since they just allow the contract to expire and bad publicity is avoided.
As for will it continue into 2021, who knows.......
