In such a context, you may have carried out several missions that went perfectly, and it is still very likely that, for one reason or another, you may encounter a problem during the execution of another project.
This problem can take many forms.
It can be an organisational difficulty, a concern for communication, a workload that is too high or too low, a difficult relationship with a colleague, etc. Thankfully, this is not very common, but sometimes it happens.
In this case, your first reflex is certainly to call the consultant who recommended you for this mission to let him or her know about your problem.
Clearly, this consultant is trained in legal interim management. These experts know how to carry out missions, and are in daily contact with other legal interim managers themselves. Therefore, they have a very clear vision of this job and the challenges it entails.
Moreover, the consultant who recommended you knows the client well, and can help you anticipate his or her reaction.
For these reasons, a discussion with the consultant is always recommended before taking action to resolve a problem that arises during the course of a mission.
