I work in a tiny company, literally just myself and my boss. The place we work from can't be fitted with a landline phone so we use our mobiles for customer orders, etc.
I'm not completely comfortable with random customers having my mobile number so I am going to get a cheap phone with a separate sim to be used just for work, to be kept at work. Very few outgoing calls/messages will be made from it, it's really just for incoming calls.
Until I get that sorted, WIBU to not answer the phone outside of work hours (unless it's obviously a personal call?). I'm just getting increasingly annoyed with work related calls coming through to my mobile when I'm either at home on my days off or on my breaks. When I'm not at work, I'm not at work!
One particular insistent customer phoned THREE fucking times in the space of 10 minutes just to find out if we were open (opening times are on the website/social media) and he was a regular anyway so should know them. I had to call him back in the end just to tell him I was not at work!
