Program of my choice states "we prefer that at least one recommendation comes from the workplace: your current supervisor or manager is usually a good choice. The other recommendation may also be from someone who has had a chance to evaluate you in a professional setting: a client, a former supervisor or a colleague from your community service or extracurricular activities"

However, I have really not discussed my B school plans with my current supervisor. That said, I am considering a client with whom I have interacted almost on daily basis and worked on an array of projects. I feel that he could bring out cultural sensitivity, team buliding and other accolades.
Other recommender I have chosen is former supervisor ( Director of program management) to talk some of other aspects

I plan to put a short note in optional essay for the reason I couldnt get a reco from current supervisor

Does this look ok or would you offer me any other advice
