Don't bite the hand that feeds you.These days, especially in government jobs, many are not showing loyalty to the job they do. They will try to be unfair and try to get some extra money in an unfair way. Is it correct?
Another type of people are there who will get help from others but they will never try to help those people who help them. Some people are still going a little far. Then get help from you and even though they can help you, they never help. This is inhuman. We should never bite the hand that feeds you. If you do that you are not a human being. Be human. Help others in case you can. Don't forget that we also need help from others. If you can help a foe then you will be a very good human being.
