You don't have to be a supervisor to influence positive change in your organization.
At Disney, there are hourly employees who have influence over decisions from management.
If you want to influence positive change you need to begin by having a spirit of serving.
If people trust you then you will gain some influence. When people want to work with you, you can have more influence on what happens.
Positive changes begin with our attitude. Have a positive attitude so people want to work with you. Then you can introduce ideas on how to make things better.
Don't wait for people to be nice before you are nice to them.
One question you can ask today to help you influence positive change is, "what more can I do for you?" Be sincere and help and you will begin to see the organization change around you.
