No but people do get too familiar with the boss and make comments or conduct them selves in ways that are not appropriate with a boss.
People do make jokes that offend CEO's or customers all the time. Social interaction is not as easy to navigate for everyone.

Do a lot of people give their boss middle finger accidentally?
Like yo, went to work, talked to CEO and give him finger, must be weather.
