bignumber,
usually airlines don't respect contract.
I have been in airlines who lied, and change the contract after you sign it, or asked you to sign or kick you out. You sign the contract, but they never sign it.
they all do that! and if you want go to court, they know most guys don't know the legal procedure, or don't want take a lawyer.
If they find you to be part of an Union, they won't hire you.I quit Balpa for this reason...cuz if you part of Balpa, it's much harder to find a job.
So your question about minimum hours?ahah, another story to attract wanabes.
