Team.

What does it mean to be on a team?
What does the word itself invoke emotionally for us?

Most importantly why when you are hired in a wage labor establishment is the word team immediately and constantly shoved down your throat?

It can be seen as another example of the exploitation of language to serve the purpose of the exploitation of people. The concept of a team is that of people working together for a goal, generally a group of people happy with each other and the goal being a mutually accepted goal. Arguably those running the establishments understand the underlying meaning of team and will use it to invoke such emotions.
"Welcome to our team! Its great to have you on the team!"

You are part of this new team, you want to do all that you can for the team because you can't let your teammates down, right? Of course.

Now take into consideration the position of the bosses aside from the masses. When there is talk of the rights of a worker, or the wages of a worker, or the schedule shifting of the worker this team fades. If you dare approach the bosses about anything of the sort you no longer play for the team, you no longer strive for the same goal as they do.

The emotional love of "team", the care and outstretching of team will only go as far as the commercial exploitation needs and wants it to go. It will serve to utilize you more efficiently because you do not want to "let the team down" and it will boost morale because you feel welcomed and have a place.
