Hello. You did not say if this question is related to any specific text or situation, which makes it difficult to answer. However, I will try to help you in the best possible way.
The word "tribulations" refers to something negative, since it is related to problems that are difficult to be solved and that causes worries and stress to those who need to solve them. A holder of a government position knows that he will have to go through tribulations in his work, but he should not be anxious about it, as tribulations can cause bad and maleficent situations. We can consider that a holder of a government position is anxious to resolve the tribulations, but not to obtain them.
