To the posters referencing Sunday evening terrors, and work-from-home burnout, I hear you. I was RA'd 2 years ago. I had an international role which meant that timewise I was 5/6 hours behind the States (Europe based). Quite a while back, I moved into a WFH role and initially it worked great. I had time in the morning to get through the email backlog and then get some real work done.
Then, when the US woke up, I would be on countless back-to-back conference calls for the next 6-7 hours, often having to decide which one of any 3 overlapping calls to ditch or delegate.
It got worse and worse. RA season or not. At peak, I reckon I was working 11-12 hour days. And that's not including the occasional AP call which would make the day even longer. And we all checked email Sat/Sun, natch.
So my friends, a little advice if I may:
Work-from-home is a double edged sword. Yes, you save commute time and cost. You can wear what you want (apart from on Zoom!) Even if you only work across a few time zones, watch your hours. Set boundaries. And don't be bullied into having meetings at unsociable hours if you work across many time-zones. Do it when it makes sense, otherwise try to avoid.
My family was incredibly supportive during the IBM home working days, but it can take a toll. Work frustration can boil over into home life which is unfair on the entire family unit.
I was just getting energy back by Sunday evenings when I realised the whole rollercoaster ride was about to go full groundhog (mixing metaphors is a bad habit of mine, apologies).
So do what you have to do during RA season, but watch your health and those close to you. Try to take a little time to step back and make informed and 'big-picture' decisions that are important to you. Burnout can be cruel and insidious. If I hadn't been RA'd, I probably would have quit on health grounds.
