Re: Not office hours? No contact
It's allowed at my place on the proviso that you allow it to be remotely wiped by the company, but given the regulatory minefield and physical security rules we have to negotiate in the day-to-day I'm pretty surprised that it's even an option.
I also don't actively hide my number from colleagues, but I don't say anything about not working OOH unless I'm asked why I didn't reply to an email/message etc. — and haven't needed to at this job. I feel like stating it upfront normalises the idea a bit less; I'd rather feign astonishment at the idea that somebody interrupt their private life to do anything on top of their contracted work :D
