50% is beyond too much of a cut. As I said, 20% would be grounds for me to leave. I don't know what kinds of places do this to people but it sounds horrible. Unless they got a raise and were not up to the new position, I can understand that.50% is quite a lot of money. I don't think I can continue to work in any organization that slashes my salary by half without any reasonable explanation or motive for that. I would simply resign.
