You don’t need to go public, companies that relying on burning people out simply deserve zero respect from their employees.

Remember as critical as everything seems it’s no longer your problem once you move on. Sure, moving on to your next job might seem to be leaving them in a lurch, but lack of redundancy isn’t your problem.

PS: The best thing you can do for your teammates in that situation is convince them to find a better job.
