Mmmm all well and good if you join an organisation and those are the rules of employment from the start.
BUT what if, for instance a largeish organisation has been operating for quite a number of years without training bonds being required, then as part of a fleet modernisation decides to introduce a new type of a/c... would it be considered fair to introduce MANDATORY training bonds for its (long term)employees effectively being forced on to a new type?
