When we are working in a team and of same rank we should always pay respect to everyone and their ideas. It is not healthy to think that you and your ideas are always right and better. We are having a common habit of keeping personal relation with boss and flattering for personal gain without the knowledge of our teammate, but in the long run this won’t help because bosses are smart enough to understand your motive. Many of us have the tendency to leak the informal discussion among the colleague to our boss or seniors to remain in good book of the boss and maintain personal relation. But most of the time it has proven wrong. One way you are deceiving your colleague and on the other hand your boss will come to know that you are not a trustworthy person. Though we should have a competitive mindset for career growth among the team member holding same rank, but it should be a decent competition not in the cost of others. Because, if you do a foul play today, tomorrow you may be the victim of foul play by others and which will never allow you to live in peace.
