Beck Flavors is an amazing company that started in 1904, creating custom flavors for the food and beverage industry. They pride themselves on the family-like experience they provide for their clients. They do many things right and that is one of them; along with also treating their employees like family. Every year they host a cookie day for their employees and allow the children to bake and decorate cookies together. As a photographer with Italian roots, I have to say, I don't believe anything brings people closer than cooking or baking together. 
Whether you are family or it just feels that way, get people together and spend some time doing things like this. And while you're at it, why not have it documented.
