I was only opining on some very possible outcomes of what KTM525 had said.
That said, what credible employer offers work with unpaid leave clauses already in the contract? Either the work is steady and they need pilots or it isnt and they want employee flexibility for free.
Anyone in the game for long enough knows that "by mutual agreement" really means "We've got deeper pockets than you, so threaten us with the employment court if you want".
Good luck to your mate. Let us know how he gets on.
