And that is for working only 9 months a year, plus 20 days vacation, plus every holiday imaginable, plus carry over sick days, plus no cost health insurance, plus pensions that are 2 to 3 times better than private pensions, plus 1 year long paid sabbaticals, plus tenure (so you can't be fired)...etc.
And if you divide the salary by the number of hours you will find they are actually paid more than the average professional. For someone to say teachers are under paid are expanding the myth.
