And its really bad if it pays a pension. If that is the case. You can expect teachers to always get the job. A pension for them is worth maybe 500K for four years. Especially if those teachers need to get up to a 30 year cap. And they can do it without lowering their pay. Sometimes they have a clause which allows them to count their average final pay as the top 3 years of the past 10. That allows them add years without lowering their average pay.
I'd love to see the school board position become voluntary. That would ensure the necessary turnover and volunteers from the private sector who would change how the schools are run. Unfortunately, the system has made people believe that the salary helps them attract the best and the brightest. Public service has become self service. The public education system exists to serve itself and the teacher's union. The public gets what it deserves for not paying attention.
In the last election, the winning candidate spent more than $100,000 to win the seat. It's nuts, but the reward is rich and the system always finds the necessary funds to protect their own.
