> it costs 5 figures and 6+ months to train a non-diver to the level of scuba instructor. It is good for the labor pool to force the shop to train a new instructor, even if they have to pay a massive cost for them to get certified, and the labor can quit the day they get certified. It is bad for consumers and the shop. I believe the common situation is a company pays for your masters degree but the two of you end up with a contract where you'll stay at the company for X years afterwards. I don't see why there can't be a non-"At will" situation for the scuba instructor.
