So I just discovered that I have been working next to the waste of oxygen that raped my best friend several years ago. I work in a manufacturing environment and I know that you can’t fire someone just for being a sex offender unless it directly interferes with work duties (in the US). But despite it being a primarily male workforce he does work with several women who have no idea what he is. He literally followed a woman home, broke into her house, and raped her. Him working here puts every female employee at risk. How is that not an unsafe working environment? How is it at even legal to employ him anywhere where he will have contact with women?
They can actually, refuse to hire them. Ex Felons have to report their conviction for the rest of their life and they absolutely have a harder time getting work.
Not everywhere, mostly that’s a thing in the US (which is a pretty shitty society when it comes to how they treat their ex-cons and consequently to re-offending-rates) or with jobs where the past could have an impact (for example if you are to work in law enforcement)
