I do not recommend it unless you really want to stop working and retire. Also, ok if you are already planning to quit for another job.
At 58, you are unlikely to find another job that pays as well or at all. You may find retirement boring.
You should stay and strive for a better work life balance. If you are financially set for retirement and able to consider erp, you can stop stressing out about work. Enjoy the unlimited pto. The company eventually lays off everyone so you are unlikely to miss out on an exit package.
