Yes, from the employer point of view, this is why vacations exist. A vacation would have helped to avoid this.
Unfortunately, that ship has sailed. The OP situation looks like burn-out. If someone has reached actual burn-out, a mere 2 weeks isn't going to be enough.
I think a lot of people are going through this now working without boundaries and no real vacation, it leads to really bad outcomes. Burn-out is serious.
Coming back from a break if it is burn-out can be worse. You hit the same walls you left 2 weeks before, with a stronger sense of what you want in your life, implicitly "not this"
Can be restated as an upside: "makes things clear"
Do you have any good suggestions for people suffering from burnout. Once they get beyond the "a few weeks off will fix this" starting stages of burnout.
I agree. A solid 2 week vacation with absolutely no contact with work will be helpful.
Coming back, however, is going to be difficult. If the workplace is setup for inescapable "nose-to-the-grindstone" KPI's that have consequences for someone that has been underperforming, it could get ugly if the OP needs more time to reset themselves.
In many places, however, a few months of slump isn't going to lead to a PIP if the OP can go through the motions and practice enough self-care to gradually get better. I think enough folks are going through this now that employers are aware it's widespread problem. Some will handle it better than others, of course.
