This is an important question and things like this can make all the difference at the work place. Here are some suggestions.
If you want to create a place inclusive, then one of the best thing that you can do is have equal representation in the leadership. So, create a model that has women, minorities, etc. Without this, the feeling of inclusiveness will not be present.
In terms of motivation, make sure that the vision of the company is clear. People need a goal to strive towards. Also there should be real incentives. Can people really move up and what must they do. Let them know that hard work pays off. Show them proof.
