A new manager has joined and he's always making calls on speaker phone! He sits right behind me so even though he has the volume fairly low it's still really annoying.
We have a meeting room literally 5m away for exactly this purpose but he can't be bothered to move his computer in there every time he wants to call someone on speaker.
He's more senior than me. Do I politely point out that we have a room for call that need to be on speaker? Wear headphones and suck it up (although then I wouldn't hear my boss calling for me when he wants something)? Passive aggressively start a loud conversation when he's on these calls so he has no choice but to switch to a normal call?
