I was griping about something at work a few days back. My boss commented about me not liking my job. I think she worries because I'm "over-qualified" and retail has a high turnover rate. I looked at her and grinned. Told her I like my job just fine, that I complained about the Army Reserve and the National Guard for over twenty years too, but kept reenlisting.
Yes, if the right job comes along, I will leave, but I think everyone would say that. Of course, it doesn't look like that is happening any time soon.
