Actually those rules for supervising women still apply today. Treating subordinate women the same as men in the workplace will get you in HR hell in a heartbeat. You might be gentle, kind and compassionate with them. And absolutely no frat boy jokes or horseplay in their presence. They are also much more emotional and stung more severely by criticism and you must accommodate that.
They can also use tears to get their way in the workplace, where a man who cries is shunned and sidetracked. White Woman’s Tears.
