I understand why they dont want you flying for someone else, but your contract surely doesnt state that you cannot engage in
ANY other work outside of RYR! Does it?
As your hours seem to be continuously reducing, you will presumably reach a point where you can no longer pay the winter bills. So its not just OAP grans wrapped in an auld tartan shaul, in front of the fire with only 'one bar' .... its OAT grads too).
So I presume you would either have to find part time work when on standby (if your contract allows) or leave RYR altogether?
The shortage of other flying jobs means that RYR hold all the aces (
pun intended)
