Warning - There is a three-letter word below that might be offensive – a slang word used to describe a persons rear end - but sometimes you just have to call it what it is. I reflected recently on the difference between work and a job. The worker sees something that needs to be done and pursues it because it advances the organization. The holder of the job sees something that needs to be done, and may or may not do it based on whether or not it is his or her job. The essential difference between these two people is simply that a worker improves the organization and the holder of a job covers his (here it comes!) ass.
