comfort zones

Do you know comfort zones? These are areas or roles that are pleasant for us, because they do not bring us into contact with challenges, because we are familiar with here, because we know that nothing can happen to us here or that we are okay here or just that we not have to work hard here. Examples are: the role of the senior expert among colleagues, the possibility to abuse one aspect, eg an additional task, as a permanent excuse, the attitude of “I don´t want to achieve here anything anymore.”
Just take a look around in your work environment.
What comfort zones are used there?
Usually it´s easy to recognize what price the environment pays for this. But what does it do to the person himself/herself?
And how is it with you? Are you also a comfort zone being?
