I think it is still considered unprofessional for a man to go into a work office with unshaven stubble. I’m not taking about close cut beards, or moustaches or groomed facial hair. I am talking 2-3day old stubble. I am also not talking about WFH, but going into an office environment where he will meet with colleaugues and clients.
YABU- I’m old fashioned and it is perfectly ok for a man to have wild, free range stubble these days in an office setting.
YANBU- It is not ok to have stubble in the office.
