Yeah, it's ingrained into the culture for lower level employees to call out people even in upper management for such minor safety violations as not using a hand rail on the stairs.

Also, I assume the complaints were for outside of any clean room environment since inside a cleanroom you are obviously wearing facial covering at all times. I do wonder about virus circulation inside a cleanroom though since there is a high volume of laminar flow and the filters are designed for particulates much larger than virus-sized.
