Brain drain in education
EdWonk posts a story today explaining why a Math teacher with 12 years experience leaves the classroom for private industry.
The contracts that education unions have negotiated across America (and schools boards have agreed to!) are heavily weighted toward seniority. When I was teaching I tried as hard as I could but I couldn't seem to get older any faster.
In recent years we have had this scenario happen with several Math teachers who left for greener pastures.
