Do teachers receive paid medical insurance and retirement in addition to their salaries?
I see you've not received a reply on this question yet so thought I'd chime in.
Like most employment questions, the answer is "it depends." School boards have flexibility in these areas to a certain degree. Paid medical for the teacher/employee - the answer is typically yes, there may be some division of cost, and it is a negotiating point for those represented by an association/union. They do not pay for spouses/dependent coverage.
Retirement can also be a shared contribution and varies by district. It would require some research but I think most districts pay all of this but there may be some that don't and state law allows that. All teachers and administrators MUST be a member of the teacher retirement system but support staff is optional under the law.
Using my wife as an example: she is a retired speech pathologist that worked for a school district for 29 years. Her retirement contribution was fully paid by the district. For many years, she declined school medical insurance and was under mine when I worked for a private employer. During her final 10 years, I worked in a career-tech school so my wife picked up her own medical coverage through her school. This also ensured her ability to get that same coverage as a retiree. At that time, I recall it was a 50/50 split of the cost but I could be wrong about that. In retirement, she pays it all. When she goes under Medicare at age 65, she can convert the coverage to Medi-Gap.
Using myself as an example: I continue to work for a career-tech school (18 years but not in the classroom) and the retirement contribution is fully paid, as is the health insurance. A stipend is offered for dependent coverage and I take that as salary (taxable).
