Eggysmom you're right I do get to go home at the end of the day and I nowhere near have it as hard as the parents of my kids once I get there.
However - I do not just work 9-3.30 term time only. 2 days a week I stay at work until at least 7.30/8pm, many times later. On the days I do leave at 5, I collect my own son and sort him out before sitting down and doing something work related - planning, making resources, repairing/replacing comms aids, report writing, keeping in touch with parents, checking emails, setting up my classroom, shopping for various snacks/sensory stuff/chalks/clothes etc.
In the school holidays I take my son into school with me and set him up with the electronic babysitter while I work some more. I'll spend 2 days of half term in school with him and then fit other bits and bobs into the time we're out having fun. Could I do fewer hours? Probably. Would I like to feel unprepared in school each day because I'd done fewer hours? Absolutely not. I work hard FOR my kids - to ensure that they're routines are met and in the hope that those solid routines being in place help them in their home environment too and therefore help make life a tiny bit easier for their parents.
Can I switch off? Honestly, not always - I'm always thinking about what I can try, what isn't working and why, if I'm out somewhere I'm wondering whether it will be suitable for any of my class and if it's not is there an alternative that would be. If staff have been hurt, I check in with them. If parents are upset that staff have been hurt I check in with them. I speak with residential staff over the weekends and have regularly gone into the residential homes in my own time and unpaid to offer support when kids have been in crisis. I'm not trying to make myself out to be some sort of saint - far from it, and I'm sure there are much better teachers out there than me but my job is more than a job and much more than school hours/term time only.
As for SW, I fight the battle WITH the parents - I fight the battle FOR my kids. I'm currently working on a transition plan for one of my kids and am fighting tooth and nail with his parents for him to get the best possible placement for his needs.
As for parents managing stress levels - as I've said, I applaud my parents for what they go through and I back them in doing whatever they need to to cope with what can be very difficult to handle behaviour. I'd like to think that they know they always have a listening ear even if I can't physically do anything and the relationship I have with them suggests they do.
