I have seen people using following in corporate emails
- He/they work(s) out of (city name)
- He/they is/are based out of (city name)
- He/they operate(s) out of (city name)
If someone is residing in (city name) temporarily for work purpose or has a permanent residence in that city where he works, can we use the above mentioned sentences?
If someone is out of somewhere how can he be in?
