What if every time some one barges into the cabin on the pretext of having some work. Who will decide, before he comes into the cabin, whether has work or not and then lets him in? We do not know what is the kind of work arrangement at your office? It sounds somewhat strange in this modern age of transformational HR where the emphasis is on connecting with people but not commanding them, you want to put a notice that sends a wrong message.True there may be some one that must be disturbing your work. If you find some people coming in and disturbing you, you can try other means for curbing such habit. For example, see whether such people have enough work on their dusk .Give them some additional responsibilities. Alott time to people for discussions so that they do not come into your cabin during the other part of the day.Deploy staff at the point of need in any other department if you have surplus staff without any work.Look for more employee friendly options to avoid it.
