Comme si comme sa. An inconvenience is almost always a nuisance but the reverse is not so. A nuisance can be an emotive response to something that is not an inconvenience. Eg a cawing crow. In this case , having a junior partner is more of an inconvenience as it requires additional actions but one May or may not regard it as a nuisance depending on your level of tolerance. If one entered voluntarily into the arrangement it would be hypocritical to then define the results of one’s actions as a nuisance generated by others. Either word would suffice.
