I'm an employer and agree with the sibling comments that this is terrible advice. Your employer isn't your family or friend and, especially during the probationary period, you need to muster up the performance needed to pass that hurdle. I'm sorry that you're struggling with burnout, but if your remaining period is a few more months, find the grit to make it through that, then you can tell your employer about the struggle and any additional support you need.

Any employer that has an 8 month long probationary period is probably not going to be the type to suddenly be super-supportive if you say you're burned out halfway through it.

I'm assuming that if you could afford being out of work for 6 months to recover from burnout, you'd have mentioned or executed that, so that best course of action is presumably off the table.

Here is a time to be consciously selfish on behalf of yourself and your family and, to me, that means hiding the problem as best you can from your employer. (Feel free to get whatever support you can from other sources, just not the job.)
