Hmm. Try that in the UK and you'll be getting sued for constructive dismissal the moment you tried "put on administrative leave without pay".
No, you fucking pay me right up until the moment you sack me, and you'd better have fucking good cause. Let alone "because some cunt made a complaint".
And yes, I've been accused of harassment before. For holding a door open for someone. Interestingly I mentioned this to a colleague and he said that at another company he'd had a formal grievance against him for exactly that too.
Zero pay because you held a door open for someone? Where the fuck do you work, and in what imaginary world do you ask a 'prosecutor' to investigate workplace harassment?
