Try retail at Christmas then you will know what exhausted is
You're wrong and clearly you've only ever done retail to make that comment! 20 years of retail here then I had a career break. Two years later I retrained as a primary school teacher.
Retail is a walk in the park compared to retail.
I lasted four years before I packed it in. Pay was shit (£24k) which didn't help when you're working 16 hour days plus working 6 days a week. Those holidays everyone talks about? 2000 word reports for 32 kids during one of them (64.000 words!) Marking, assessment. Planning. I spent every 'holiday' actually in school at some point. Building air raid shelters for WW2 project (you need to inspire the kids and there's no one else to do it), re-doing display boards in the classroom (technically a TA's job, but they have a ridiculous amount of other stuff to do too, so if you want it doing, quicker to do it yourself) I could go on but basically it was the most all consuming 'job' I've ever had.
Anyway. I was an amazing teacher ! Even Ofsted said so
I knew I was good. Yet, I left. Still feel awful about walking out. You're all right about one thing. It will soon be only the crap teachers left - those who can't get another job elsewhere. The most annoying thing - I still owe £9k of loans!
Nurses/Docs etc don't have to say how hard their job is, everyone knows. Equally, everyone thinks that teachers work 9-3 and have loads of holidays. Maybe if people started to respect the teaching profession, you wouldn't hear teachers moaning?!
