Speaking from my experience it is the out of work experiences that make a team motivated, I have seen various attempts done by management to try and motivate teams. if the work is boring or repetitive, there isnt much you can do within the confines of work. to get motivated you need stimulation knowing that it isnt just another management engineered attempt to get people to work harder. I find that drinks after work, and lunches out, work better than anything that can be done in work time. how can you relax and get motivated when you have to either watch what you say or do.

Getting more involved in the business or having the opportunity to help others does help, but it only works so far and I have yet to see most companies allowing that sort of freedom.
