Difficult Career Decision

You summon the war god inside you and attack every person, by name, that is responsible for the issues that are so damn obvious to you and probably everyone else. You will either get an honest chance to fix things or not. Either way, you are engineers, for fucks sake, don't behave like you can't handle whatever comes next ...

You are not trying to be a hero or anything and you obviously don't want to be a coward and most importantly, you want to act responsibly WHILE KNOWING EXACTLY WHO AND WHAT THE HELL YOU ARE DEALING WITH, it's a company with gears and belts and whistles, damn it, ... and now ... with some shitty humans that have been making bad decisions way before they became your colleagues ...

If you are at your limits, your fellow engineers might get there, too ...

Just treat this whole thing like it was a problem that you and your team face all the freaking time, except this time, there is also sabotage (terrible work ethics, show no respect for its employees and triggers all the red flags) ...

Speaking from experience, if you were a strong manager, your team would likely follow you wherever you end up going. So I wouldn't worry about leaving them behind as much as focusing your efforts on finding a good next opportunity where the employer would have the capacity to bring on more resources.

Nobody is more important than yourself so do what is right by you first above all else. Other engineers will do what matters to them when the time is right. You're not their mom, just their manager.

I think that you have to look after yourself initially, like putting on your own oxygen mask before attempting to help those around you. You may be able to bring across some of your team members in due course.
