I work in a fairly senior role- salary c.£70k- and I'm constantly busy at work- my diary tomorrow is back to back with two scheduled toilet breaks. I am back in office and company doesn't like home working. My DH is a lorry driver- earns half as much, works just as hard. Neither of us get paid parental leave but i can work from home. Nursery still charge £63 a day despite DD not being allowed in 
Just had notification that youngest DD (3) needs to isolate until Tuesday. I can do my job from home but it's going to be difficult to manage with a 3 year old at home. DH has just assumed I will do it because "it makes sense" but doesn't realise when I'm working from home I need to WORK and a meeting can't just pause whilst I wipe DD's bum or make her a juice. Work are pissed off that I'm taking more 'time off' LOL and have asked me to share the split with DH. He says his boss just said no, so that's that then. To be fair, in his industry it would be usual for him to be given two weeks notice and get sacked- in mine, unheard off but it's career limiting to not be flexible.
I just have had enough. I have always worked, always juggled childcare/home life but i just can't do it anymore. There's no separation between work and home and i feel like I'm letting everyone down. I am exhausted. I can't think of much worse than another week stuck indoors with a three year old who doesn't sit still long enough to catch covid let alone let me conduct a client care meeting for 45 minutes 
Sorry, rant over but happy to lend an ear to anyone else in the same situation!
