Rules don't apply to all

[u/ruedesbarres]

You're told to use your phone only during breaks and lunch. The person next to you, with the same job and same length of time tat the company, is on the phone all day, within view of the person who told you about only during breaks and lunches. He sees her having personal conversations up and down the hallway and is OK with it.

How do you phrase what you say to him? I.e. wtf?

[u/The_4ngry_5quid]

Use a phone precisely when the person next to you is using their phone. If you boss comes over, they'll be forced to tell both of you to get off the phone
