Ali is sitting at his desk, clearing out his email inbox. Tamika, a colleague, has sent him a question about a client they share, and Ali isn’t entirely sure of the answer. So when he replies, he figures he’ll cc their team leader, so that she can chime in if he’s gotten anything wrong. Ali thinks nothing of it — it’s a collaborative work environment, and transparency is a good thing, right? But Tamika sees it differently. Five minutes later, she’s at Ali’s desk: “Why did you loop our boss in on that email? She’s going to think I can’t handle clients on my own!”
