honestly, awful experience at my firm and I want nothing to do with them again. experienced some post mat leave discrimination/mistreatment that exacerbated my PPA/PPD (treating it/it’s under control luckily). i am not interested in legal action, just want to leave and move on. Have another job. I know probably not ideal, but can I just give my notice to HR via email and cc the group heads? or send the email to them separately?
