Every leg on a day flight you ask them if they have already joined the union.
If he says no..... he don't fly
Is that really a valid reason for a Captain to replace an F/O? With that method you are replacing a bullying management with a bullying captain.... Sure fire way to improve moral and CRM.
Surely union membership is a matter of personal choice, or do you want to go back to the good old days of closed shops?
