I have just come out of a meeting with my line manager and told that I am no longer allowed to work in the library every morning. The "library" is actually a small meeting room with desks and a few books where we are allowed to work quietly and talking is banned. I work in an open plan office so this room is like heaven. I spend the morning there powering through the important work that I need to focus on, go to lunch then spend the afternoon at my desk.
So apparently my routine is sending the wrong message, somehow. I don't look like a team player, I look like I "hide" in there too apply for jobs, and other ridiculous allegations. Someone has been using that room to do some online shopping and I suspect they think that I also piss about in there not doing work.
But the thing is, this is the only time I get any meaningful work done. I resent each afternoon spent at my desk because I can hear every conversation and it is distracting. 100 people taking calls, talking to each other about clients or their weekend plans - the chatter is overwhelming. A task that should take me 10 minutes can drag out for an hour. I know some people listen to music but I find that too distracting.
I just need peace and quiet. Why is this too much to ask for? Why am I being punished? 
I know from prior experience that I'll get very little done if I am forced to sit at my desk all day every day.
Has anyone else been in this situation? How do I deal with this?
