How to be a competent subordinate? When a leader encounters a problem, he should take the initiative to help the leader through it, even though it is not his job, if it is within his ability.
Colleagues should be cooperating with each other, not competing with each other as "enemies". If you think of your coworkers as stumbling blocks to your own development, it will be difficult for you to gain a foothold in the office, and of course, it will be even more difficult for you to develop. Remember that mutual benefit is the basic prerequisite for collective acceptance.
