Society expect it's members conform to a certain extent. Such a getting to work on time, stopping at a red traffic light...
To 'fall in line' can mean lots of things. If it is basic stuff such as being punctual, wearing a uniform- whatever, most are usually okay with that. The difficulties can be when individuals clash- perhaps over personality or the work culture. If doing 15 minutes extra unpaid overtime every day is expected, or getting coffee for co-workers. I think normal is defined by the place in which people are living/working. A normal environment in a prison is much different than a normal home environment for a young married couple.
