The teaching profession isn't uniquely impacted by this pandemic.
I struggle to have massive sympathy given my child's school shut in March and provided nothing beyond a couple of a sheets of A4 (pulled from free internet sites). I was expected to educate my child, whilst working full time dealing with a global pandemic (my job has global scope). Yes I am expected to meet targets just like I was pre-covid - in fact a whole list of extra targets have been added to respond to the impacts of Covid. If I had not being doing my job, I sure as hell would not have been paid during that time. My child's teacher was able to completely abdicate their responsibility from March onwards - something I still can't fathom. I have medical conditions which put me at high risk, as do a number of my family members. We had deaths in the family, funerals which only a hand full could attend. We were unable to visit dying relatives. My grandmother is slipping away in a care home as we speak - they have shut their doors and no one can visit.
Everyone has suffered, some have rised to the situation and gritted their teeth and carried on. I fake it half the time, but I try to model resilience for my child as I cannot expect her to keep going if I choose to give up.
Teachers don't have the monopoly on 'difficult' right now. Its shit for them, it's shit for all of us - including the children who rely on teachers. I admire nurses, doctors, emergency services personnel etc - those who throw themselves into the firing line. They have it a lot harder than I do, along with many others in similar professions.
There's a lot to do said for being grateful for your lot at the moment, rather than complaining about how hard it is.
