Alledgedly a NY based Chasideshe kashrus agency wished to make an unannounced visit. Rav Weismandel instructed not to allow them in. That outcome would have been devastation to him, so he preempted with the resignation.
BTW-What is a chasideshe Shechita? What is a Yeshivishe Shechita? What is a Shechita Mehuderes? Evidently they are not the same.
