Firstly - it’s not all schools are offering lie ins.
I enjoyed my teaching career 34 years of it. I retired 8 years ago but still feel qualified to speak.
At times it is an inflexible job - at some schools it’s hard to get time off to go to the doctor, dentist etc. Friends getting married in the week - tough you're not going. Want to see your own children at their sportsday etc - tough in many/most schools. Funeral - ok if its your own parents, possibly in laws, possibly grand parents. Others probably not.
For me, and others(?) the greatest stresses came from the ripples spreading out from OFSTED and results tables.
Or more accurately Heads’ interpretations of what was required.
A deal of writing up of things that would never be read.
The pursuit of unobtainable exam grades for decent, but not that academic, pupils - and the stress of explaining them to the Head in the September inquiry.
As a secondary teacher I was more insulated from parents than a primary teacher.
Retention and burnout is a big problem and so anything that help, and from a schools point of view is cheap, is welcome.
In my last school we had a couple of things - not sure what the take up was though. Laundry and car repairs! They’d be taken away and washed/fixed. We had to pay though. Cakes on special days even if they were Morrisons 10 for a quid doughnuts!
Looking back at things that helped - A head that knew my wife and children's names, a deputy who was particularly kind when my fil died suddenly, another deputy who said take off any time you need when my dw had cancer.
SLT who will insulate you from awkward and belligerent parents.
Those who understand that you are not on top form every minute of the day.
SLT who lead from the front - not their offices.
An environment that allows you to have a proper lunchbreak (and visit the toilet as and when needed)
My, adult, daughter gets a day off a year to do what she wants. More would be nice but its a start.
