I cannot understand why this is being downvoted. We would have all been wearing N95's long ago if they weren't difficult for frontline workers to use 8 hours a day. People care about their own health by and large. They will use reasonable strategies for mitigation and reject those that are cumbersome.

The people pushing N95 mask requirements are not the same people required to wear them 40 hours a week. The people pushing non-N95 mask requirements are confused about the effectiveness of non-N95 "masks".
