This comes around to how we define myself.
In a conversation in our data center one of my coworkers said her job is her life. Her self-esteem depends on how well she did her job and she ia fully dedicated to the company; she had no husband or kids because her career didn't leave her time or energy for it. Another employee said his job was what he did not who he was; it was just a paycheck.
I guess I walk the middle road; I try to find a life balance between home and work life. My job is important to me but so is my life outside of work.
My dad was a workaholic to the extent of me not seeing him much. He often worked 14 hour days and usually worked 7 days/week though usually on Sunday he "only" worked 8 hours. I decided that wasn't the life for me or my family. Partly because I'm lazy compared to him and partly because I want to see my daughter grow up instead of just being a good breadwinner.
You talk about going to the bar while your at work because you cant wait to get off, get some drinks, relax, and hang out with friends. Once your at the bar you talk about the problems and stresses at work because you now have people around you will agree with you and be on your side....ultimately making you feel better and like someone else gets it.
True, I feel I talk a lot about work, but it is not because I dread it, it is because I have been called a workaholic and all I seem to think about is work. Not much of a life, lol.
I'd say because they have very little interesting in their lives.
