How to be a "Team Player":
As you go through your work day, be on the lookout for those moments when a minimal amount of extra effort on your part can make someone else's job a whole lot easier.
You can be sure that all of your co-workers will repay the favor by looking for opportunities when, just by deliberately slacking off for a few seconds on what they're supposed to be doing, they can screw you over for minutes ( or hours! ) to come.
That's called "teamwork!"
I'm fifty years old; you wouldn't think I'd still be surprised by how consistently this is the case.
