When I broke down and got sick I started cognitive behavioral therapy and among the things we talked about was expectations. It turned out that I didn't really know what my boss' expectation of me was. What I thought his expectation was were one of the things that broke me. And it was all fantasy. Lesson learned. Be frank and honest, don't be afraid to talk to your boss. Make sure you get answers that are explicit and something you understand. Make sure it's not cloudy company and management pep talk that you can't even remember a few minutes after the meeting.
Me and my boss talked a lot, and I ended staying in the company, but switched boss. :)
Speaking on behalf of all non sucky bosses don't let issues fester - just tell us what's up. Maybe we can help.
Also if you aren't going to take this approach (if you have the luxury).
That said, even the most cold-blooded bastard is going to make an effort to keep any middling-or-better employee right now. It's too hard to find competent replacements.
So it's in the developer's interest as well for the manager to figure out a way to reshape his/her job to make it sustainable (and thus keep the paychecks coming) rather than just saying "uh, sure, go deal with your problems, take as long as you need; when you run out of money we'll still have your job here for you."
Plus -- "first newborn in the house" is something that causes upheaval for maybe 6 months or so, and then life settles down again. If you have a supportive/flexible work environment then "up all night with a crying baby" here and there (before the baby grows out of that stage!) doesn't result in crushing stress and visions of disaster.
Edit for more context -- we have a developer who works part time and sometimes takes long sabbaticals -- switching into his alter-ego as a theater director. It's quite a different sort of situation from someone who has a newborn and is burning out.
Ha! That's fine until they get to 8 months and stop sleeping through the night again (which apparently is a common thing). A few weeks of chronic sleep deprivation can absolutely destroy your ability to do anything vaguely brain-work-related.
I have two kids, 3 and 6. The second was hard, but we knew what were getting into, largely, and how to survive it. The first was... rough.
I'm not sure about sleeping through the night stuff -- we did the co-sleeping thing, which helps a lot! But still, by 8 months I'll bet the parents would have some strategy in place -- maybe "hey, tonight's your night to wear earplugs" coupled with strategic naps.
If you're not going to do it, who will?
The work might wait a week or two (vacation), but do you really think the clients will be OK waiting months (sabbatical)?
The only industry where it's acceptable to just take off is within academia and that's mostly because most of the teaching is done by staff that would never have the option of a sabbatical to begin with.
Time off is not a solution. The problem will simply resurface when the person comes back.
The solution is to re-organize the work. Hire an additional person, if needed. Add work that the employee will enjoy and that will be relaxing. That's a solution.
If the company isn't interested in solutions, then the solution for the employee is still not a sabbatical. The solution is to quit and find a company that isn't so myopic.
And if you're hit by a bus, then what? The company goes under? People shouldn't exactly be replaceable, but they also shouldn't be carrying the entire company on their shoulders. No wonder they get burnt out.
He talked me off the ledge and within a day had transitioned my troublesome projects to others and moved me to a four day work week to recover. He had to run this by manager's three levels up, do an insane amount of HR paperwork (fulltime -> not fulltime, pro-rated salary adjustment, etc.). All this happened in a space of two days.
I stayed on a four day week for a couple of months. It was magical. He retained my reduced workload when I came back full time.
His first comment when I initially cracked - "you should have come to me sooner".
The quick reaction, sympathy and support I got cemented my loyalty to an outstanding manager.I'm still here a couple of years later.
