Is it reasonable for us to suggest that teachers working long hours (grading doesn't do itself) who are professionals get a crappy summer job? When you divide the salary into 190 days the tacit implication is that their pay should be cut and they'll be able to make up the difference. No one is going to pay someone a professional wage seasonally.

I'm not opposed to requiring that they put in the same number of hours over the course of a year that everyone else does but it's not like they're programmers who can go freelance for a few multiples of their standard salary hourly rate.
