Is this okay?

What is your opinion? Is it acceptable to touch a colleague during a conversation? Or for a company to ask employees without children to not take days off during school holidays? Could one ask a colleague with tattoos on his arms to not wear short sleeved clothing?

Everyone has the right to a safe workplace. But what that means exactly is different for everyone. What behaviour do you think is really unacceptable? On the basis of 100 situations, discuss (unacceptable) behaviour in the workplace. This will certainly prevent personal damage in your organization.
