b mi baby,
There is nothing you can do to stop it. If the company does its deals with a union, in order to set up a working system with its employees, then non-members will benefit. You can't stop it. Thats democracy. Be thankful you have democracy.
Having lived in a country where democracy was taken away, I am thankful I now have some choices. They might not be all the choices I want, but I have choices. What you want, b mi baby, is for all pilots in your company to be BALPA members before they can join your company. Think about it, thats what you're asking for. Thats restrictive practise. You weren't around in the awful union-controlled times of the seventies were you? You have always been the beneficiary of democracy, haven't you? I suspect you aren't really appreciative of the life you actually have.
Think about what you have now, really think hard. Then look at your opening post and see it for the shallow throwaway that it is. You've led a spoiled life but there is always time to change.
