Parents have had to try and do two jobs at the same time with zero choice in the matter
I completely understand that working parents (including teachers teaching one subject to a certain phase and having their owb children in another!!) have had more to deal with. But encouraging and engaging the number of children in one household (and taking an interest in, and ensuring, their learning really does come under the remit of good parents) as opposed to thirty at a time, when each child's class teacher has provided the materials linked to the curriculum, facilitated the explanations and marked the work produced, isn't also doing a second job.
Teachers themselves had additional demands on their time simply in work (without considering their own children) in order to make things clear and accessible when not physically with students. Calculating grades, checking in daily with vulnerable children, delivering meals, supervising KW children were all in addition to the continued work setting lessons, responding to queries and marking work produced, but trying to use technology.
No one has had a choice, but that included teachers.
When I ring my bank and there are long delays and shortened hours available and the automated message tells me to put up with noises from families/pets as colleagues are working from home, I accept it. When I stand outside a shop in the rain while others browse for ages, before having limited choice and being asked to scan my own shopping by someone standing safely behind a screen, while other customers squeeze past me, I don't blame the staff or feel I'm doing their job for them just because my life is harder!
