where I work certain people greet each other as ms williams and mr jones while others pat and randi and a certain ethnicity greets each other daily with a kiss on the cheek.

“With all the stories of inappropriate conduct and worse amongst frum co-workers, is there too much friendliness with each other?”
IF those stories are true then there is too much “friendliness”. I think someone is making a mountain out of a mole hill.
