If someone working in a public institution takes the civil service examination, what impact will it have if the leader of the institution finds out? How to avoid adverse effects?

Has your intention been known by the leader? If so, there will definitely be an impact. It is impossible to avoid it and can only be compensated to the greatest extent. Mainly affects your promotion and interpersonal relationships. Because the leader knows about it, it means he knows that you are a restless person, and no leader will promote a restless subordinate who leaves at any time. At the co-worker level, it’s mostly jealousy. If you want to take the civil service examination and distance yourself from them, some people will alienate you or do things that are harmful to others and not beneficial to yourself. If you can pass the exam, everything will be easy. If you fail the exam, they will laugh at you for not overestimating your abilities.

If you want to make up for it, the leadership level should explain it and express it appropriately if necessary, which is equivalent to expressing your heartfelt feelings. As for colleagues, get closer to them every day and say things like "It's just a matter of fun, there's basically no chance" to reduce their jealousy.

But if I were you, my leaders and colleagues would know about it anyway, so I would study hard and try to pass the exam as soon as possible. Because the impact cannot be completely eliminated, there is no value in leaving it behind. Second, let them know you are capable. Third, it is better to develop on your own without having to stay in the original unit and suffer a run on it.
