A comment I made to Sean concerning the 50% of teachers who quit the profession within five years:
Sean, I don't doubt the truth of your non-anecdotal fact about teachers quitting within five years. But let us think it through a bit. Since it is likely you can't, I will do it for you. Compensation for teachers in the public sector is back loaded. The payoff really comes later after many years of service. Initially, salaries are modest. But after a while, teachers cash in with higher salaries, the better jobs, pensions and free health care for life in many cases. So young teachers have to make a choice within a few years. Will I accept a relatively raw deal now for a big payoff years down the road? Some will, while the truly talented will in many cases move on to other professions where their value is not defined by the passage of time. It would be interesting to see how many teachers leave after they are well down that road. While many have probably quit in effect, they muddle through, bide their time and await the payoff. Not exactly the best system to secure great teachers, but what would you expect from collective bargaining?
