A lot of what you're posting is inaccurate.  District donations for health care have risen much more slowly than costs for teachers (AEA contract).  AEA members moved to a plan with higher deductible and co-pay AND are contributing more from their paychecks than they have in a long time right now.  For some teachers that has meant a paycheck that went down from one year to the next as premiums have risen.  If you compare policies, there's no question the AEA health plan is the best deal the District has going and they would save money if more employees were covered by it.
The "one time cash bonus" was money that was not built in to the contract (not repeating) and outside the formula for retirement.  It helped get a little more cash into pockets and saved the District contribution to retirement plans.
ASD - even with layoffs - will have to go out of state to recruit people into positions requiring specific credentials.  Think about that for a bit. We compete with Ca.  Not our employees
