Can I sleep with my 43 year old female boss to advance my career?
That doesn't sound good. What would happen if you stop sleeping with your boss?
I'm getting out of my boss's good graces.
Apart from it being wrong to sleep to advance your career, it is not good to sleep with people you work with. If something goes wrong it could affect your work.
I'm fine with being considered a hoe by others.
It is okay to not care what others thing but it is still inappropriate to sleep with co-workers or the boss. Either of them would be bad for your career.
