Bored_on_the_Job said, “I wonder if HaRav Neiman had the personal experience of working in a mixed gender environment, especially with goyim.”
Joseph replied, “Do you wonder if HaRav Elyashiv had personal experience in gittin or geneiva….”
I don’t see that as a good comparison. As an employee, you are expected to be a team player. You may easily risk your job by ignoring others. Did HaRav Elyashiv risk his position by following such “Halacha”? On the contrary, it helped him.
Similarly, I once received advice from a Rav who had no idea what a work day was like. He thought it was 9-5 and paid “the big bucks” as he called it. It was more like 9-7 and paid decently (like 60,000-65,000 – 15 years ago) but not “big bucks”.
While I agree that gedarim are needed, some of the ones mentioned are unrealisitc.
