People who laugh at things that are not funny show their weakness and telegraph to others a low self-esteem. Those who go along with things they know that are not right lack character and integrity. Don't be double minded. Loyalty is a must if you want to gain power with people. A lot of people in supervisory positions make the mistake of thinking that loyalty is only required by their subordinates.
Loyalty is a door that swings both ways.
Loyalty is not given. Loyalty is earned. Loyalty starts with you.
