Have a some sort of board (white board, black board, or even a shared document) that everyone in the company can access. On this board will be a minimum three columns with several rows. The columns will be "name, want, offer". It works like this everyone puts there name on the board then lists something they want and puts something else they can offer to the office. (Example: Maddie , wants: to learn another language, offer: can help with excel). This will help bring the office closer and may help fellow colleagues make friends they never thought they would. It also eliminates employees being forced to participate in it.
