Stating an objection to supervisor

Some time ago, I listened to a podcast in which Mark made the point that, once a subordinate has stated his position in objection to his supervisor's position or decision, then his only remedy is to go along with the decision or to remove himself from it (assuming the decision is legal and ethical).

I would very much like to find that podcast again if any MT members have recollections better than mine.

Thanks in advance...
