This sounds like an unproductive environment?
Like... a boss shouldn't need to call reports on their vacation, that's why engineers build systems and automate things. Being unable to fill a position in 8-12 months suggests the hiring process is broken.
I'm all for the importance of hard work, but I'd suggest an org like this is working hard but not smart.
8-12 years is enough time to train an 'unqualified' candidate, or get them the requisite licensing/certificates/etc, assuredly.
On call while on vacation? You're understaffed then; even in the face of catastrophe you should have an on call rotation. If even then you still end up having to contact one person, you have too much knowledge siloed.
Etc.
A crunch once in a while is fine. Some deadlines are unavoidable. But brute force as corporate culture will inevitably lead to shit results. Especially in so-called "high-stakes environments" , where mistakes carry severe consequences.
On top of that, burning out can nullify years of "personal growth". A wreck is a wreck, no matter how many seas it has sailed.
Well, the Navy Seals, who know a thing or two about high stress and deadly serious work, popularized the expression "slow is smooth and smooth is fast."
But unless you're an emergency room doctor or defending Ukraine or developing the next COVID19 vaccine, come on, nothing you're doing is that important.
What you're describing is not a thing that most organizations have any real need for, it's a culture of fake emergencies.
and speed is the economy of motion.
> where you WILL feel pressure to deliver products by deadlines
vs.
> where you WILL go 8-12 months without finding a qualified candidate
Sounds like a pretty good position to set some boundaries as an employee.
