Here is some interesting sharing. I was working with a very renown company here in human resources as senior executive. I was responsible for training and development of employees there (roughly 350 employees). 

For six years I was there and from beginning I was keen in development of these people, particularly those who work on machines. I used to visit their families, teach them English without any fees, cook food with them at their houses, see movies and the like. Being a training I also used to train them.

I had decided to leave company and just few days before my last day, employees on machine were on strike. I met the union leaders, told them I do not want to see strike when I am leaving. It was genuine request. They all discussed within themselves and they decided to withdraw the strike.

My experience in this episode was that if you work for others without any expectations and with genuine efforts, people listen to you and they respond positively.
