Smart employers will recognize that this is the path to retaining good employees who are in really trying circumstances. But, it requires the ability to think long-term.
Look at what leave you have under your current terms, make a plan to take it, get approval of the plan, and stick to that plan. I did not take all my leave in 2020, but I will not be making that mistake in 2021.
If you don't have any leave, then see what you can negotiate and consider unpaid leave. Lots of employers will push back hard, but when push comes to shove, what are they going to do? Fire you? Well, then, at least you'll get a break
Another poster here. I had a previous employer who pushed back. They were just unreasonable, but it was more from a control-freak boss than from top management. I ended up taking FFCRA leave expecting I wouldn't need it past the summer. Little did we all know...
I'm now at a new org that is a lot more flexible, but I'm burned out from running back and forth between my kids' devices and my work laptop. My memory isn't what it used to be, I'm tired and moody. I remind myself every day not to get mad at my kids when they're just being kids if they distract me because it's not their fault we're all cooped up and I have to make a spreadsheet when they're asking for snack.
I'm not usually like this. It's not us, the parents, it's the situation. We're being called on by schools and employers to accomplish something absolutely ridiculous. The system is broken. I pray every day the kids are back in school full time this fall. There is no way this can go on for another school year.
