It is a myth that civil service is a relaxing job. It is not. Just because you hate the gov does not make it so. During this Covid period, everybody is overworked. Tight deadlines, little prep time, complaint-prone public, a zero-tolerance unforgiving work culture, and a grading system that pits everybody against one another. It is a high-stress job. The only plus point it has is that they don't fire ppl in their 50s. There is job security for you to work till 62 or 67.

If the OP's goal is to relax, the ugly truth is that you have to retire. Everywhere is the same.
Whether you become your own boss or an employee, the stress is there.
