Try to avoid this phrase - "It's not my fault"
Is the phrase It's not my fault Ok to use frequently at the workplace? Should you fight tooth & nail and simply disown responsibility with this phrase or explain the facts when a mistake is done & suggest remedial action? What would you do?
In any organisation, there would be a certain work culture and we should get adapted to it. We need not own responsibility for every mistake that occurs but should not try to find an escape route by simply saying, "It's not my fault". Rather, a polite way of convincing others with facts would not affect the harmony in the team. It is such a phrase which would affect the team spirit and make you isolated in the team.
Most successful team players are those who take the lead in convincing the reasons for a mistake and how to take remedial action to correct it. One should avoid using such phrases while working in a team and try to create a congenial atmosphere otherwise it would become contagious! Isn't it?
