Untrue. I've listened, and continue to listen, with an open mind. However, I haven't found the arguments being put forth to be very persuasive. Being unconvinced is not the same as "not wanting to hear".

If an employee's productivity has become unacceptable, then you address it with that employee to correct the situation. If it can't be corrected, you fire them.

This is no different working from home than working in an office.
