I get where you’re coming from and sympathise, but there are currently loads of these threads going on and all have the same theme - what a bunch of evil employers people have.
At the end of the day, this is an awful, unprecedented situation and many employers are having to try to secure the future of the business in order to protect as many jobs as possible. This is in the background of uncertainty, ever changing guidance and unclear rules, along with trying to accommodate WFH measures (which in many cases is reduced productivity) or other H&S processes and expenses. They will also be trying to catch up due to external client demands, which are not always the most reasonable, and worried about everyone saving up annual leave and taking it in bulk in the last 6 months of the year, which will stress the staff left working. Add that employees moaning about other staff on furlough of WFH with reduced productivity. I highly doubt employers are sat there trying to think of ways to make parents lives difficult. They are trying their best, as is everyone.
WFH has been a real help, but in many cases it is not the same as being present especially with young children in the background demanding attention. I know - I have two pre-schoolers.
Before I get piled on, I know some employers are rubbish and unhelpful. But many comments I have seen seem to refuse to acknowledge any responsibility on parents to try to work with their employers. A refusal to use annual leave to look after children is a common one - that’s what leave is for, it’s not all holidays and sunshine. Or a refusal to use available childcare.
I genuinely do sympathise, but with everyone in the situation. Not just parents.
I don’t know what the answer is in genuine cases where there is no alternative. Not very helpful I know.
