Generally, it is a bad policy to date a coworker at any job.

I do find some coworkers attractive and will let the friendship progress however it does.  A definite no-no for a store manager to date a hourly employee in any business.  Several people in my store have met their mates working for Kroger.

If the relationship goes bad, the break-up is nasty, then the work drama will be unbearable.  Especially, if the ex is a crazy fool.  One or both persons will lose jobs eventually.  Think flat tires, broken windshield, keyed paint, domestic violence with weapons!

The above is for close intimate relationships. 

If you want to hang out with someone for bowling, lunch or a movie with no intimate expectations, then that would be ok except for with a salaried manager.  I hang out with a coworker and we have a decent time.

If 2 checkers or employees on the same job classification date, more power to them. However if a manager dates someone lower than them problems can and will arise. Even more so if they keep the relationship secret. I think if management is found dating a "low level" employee, they must either 1) transfer to a new store, or 2) voluntarily resign. If management don't want to do either of those things then they can be forced to resign. Again, this is speculation.

I heard Bill Gates' wife describe how she met him on a radio show.  She was a guest on NPR on one of the game shows and described it.

She was a secretary for Bill Gates before Microsoft took off.  He asked her out.  Her reply was she wasn't sure.  She asked her mother if she should and the mother suggested not to.  She went anyway and the rest is history.  Her version was funnier tho.

Do NOT ever date a coworker.

It is the worse experience I have ever been through in a relationship. I am still with the guy, but it was **** the whole first year (when we were working together), and there still are some consequences. I was very unlucky also to be in a department where 30 single young women worked with one male as their director and he was hot. He liked me and asked me to date, I said yes, in my naïve head I didn't realize what I was getting into.
For the whole past year I had to endure all the women hitting on my boyfriend and him telling me we shouldn't tell anyone about our dating because it would look bad on him. I know, I have been stupid. There is nothing I regret more than having said yes to that date, please if you are thinking about it, there are two options: DON'T or Do, but one of you changes jobs right away. YOU DO NO **** WHERE YOU EAT.
