You are better off checking with your state's labor board than with this
news group.

Most states have minimum wage laws and they insist that you be paid for time
spent instructing, attending mandatory meetings, manning the pilot shop or
desk, locking up at night, etc. They also insist that all such time be
included when calculating mandatory overtime.

Flight schools attempt to avoid these laws either by flagrantly ignoring
them or by insisting that their instructors are 'independent contractors,'
which they are not. Flight instructors are not management, either.

If you think you have a legitimate beef, file a complaint with your state's
labor board.

Flight instructors are grossly underpaid as it is. Just because unfair labor
practices are common does not make them right.
