My new company does not currently have a break room. Seeing that there is an unused room right next to our workspace, I asked whether it was possible to turn it into a break room.
My superior seemed pleased about the idea, but the higher-ups were lukewarm. At first they said that they would not be able to allocate any budget. I then suggested that my colleagues and me pool the money to furnish the room little by little, but that did not seem to sway them.
After a bit of probing I learned that the higher-ups are not convinced about the potential benefits of a break room. They are afraid that their employees might get tempted to spend too much time in it and laze around.
On the suggestion of my supervisor, I am writing a small document in order to explain what we would like to do with the unused room, and what good would come out of it. How can I properly convey to my employers the benefits of having a break room in the workplace?
