I hear this day in and day out from all walks of life.
"I'm JUST a factory worker. (or insert any job here)"
&
"It's JUST a job."
I especially hate this last one. I have always been one to be proud of the job I do for my employee. Even as a factory worker I never thought of it as JUST a job. I always felt that I was an important cog in the wheel that supplied customers with products that in some and most cases, they depended on. Most employees just show up, do a job and go home.
