Smoking workers the bane of their colleagues

I WORK for a company with about 60 employees, of whom fewer than 10, including the CEO and director, smoke. To ensure that the smokers do not spend too much time smoking outside, our director built a room for them inside the office. However, the smoking room was poorly built and does not prevent the cigarette smoke from seeping into the open office space.

To make matters worse, the CEO and director smoke in their respective rooms. The cigarette smoke seeps out through the gaps in the door and whenever they come out of their room. It is the same with the smoking room.
