He went away on leave this week. He's not going anywhere, he just wanted a week off.
On day two he came back into the office to look at his computer. Brought his wife in and everything. Spent half an hour here saying he needed to "sort out the computer, it's been bothering me". On his day off.
Then we realised he had diverted his work phone to his mobile. So any clients calling the office would get straight through to him. He did this intentionally.
We've since noticed he's responding to the chat in Slack (messenger app). Guy is sitting in a coffee shop somewhere by himself responding to work banter on his week off.
Don't be like this guy.
There's nothing wrong with a man liking his work or work friends.
