Poll in a moment. Talk amongst yourselves till then.
I’m currently unemployed, but at my previous place, relationships between coworkers was totally against the rules. However, if you happened to be an employee that made a lot of money for the company, the rule was ignored. If you were a lowly peon, you got the boot. This double standard was pretty much the rule for all the rules. Theft too. That’s why I hated it there and am glad to not be there anymore.
I used to work for a major corporation…the rules explicitly stated that one could not date their co-workers, or even work in the same dept. as someone they were related to, meaning spouses, siblings, etc. However, we had a low-level manager date a guy from a different team (however they still interacted on a daily basis) and the bosses said it was ok as long as she never “managed” him and didn’t discuss it at work, however she was a loon, it caused a bunch of problems, she ended up quitting and the guy got mad whenever we said her name. In another instance a manager was dating a co-worker from the same team, and it was a very well kept secret, however they were both fired because supposedly he was misusing the employee discount to buy her stuff. Neither of them did a good job though, so perhaps management just found a convenient excuse to get rid of them.
I am now working for a very small company where there are only 2 girls (including me) and the boss is dating the other girl! And we have the same name! She’s a nice girl though, I’m in a position above her, and we don’t interact much actually…we work opposite each other. I hope it won’t result in drama, but if it did, it would be on her end, I hardly even talk to the boss himself.
No dating of coworkers in your direct report line or whom you might have to audit. They’re really good about providing lateral transfers when needed to avoid conflict. Just don’t abuse the priviledge.
Clients I’m not sure about, but we’re the major hospital in the region so I’m sure there’s guidelines.
I’m a gummint civilian employee and not only is there no rule about “No dating” - we have a number of married couples who met here and continue to work here. I expect something would be said if a supervisor or manager was dating a grunt, but it’s never come up, so who knows…
We also have a number of military folks and their rules are pretty clear - no officer/enlisted fraternization. Period. Lucky for me, that rule wasn’t in effect 27 years ago. I was an officer and my husband was enlisted. Of course, after I had the audacity to marry him, there were officers in my squadron who would not speak to me. Whatever. My sweetie and I finished our obligated time and joined the civilian world.
Yeah, the poll doesn’t take into account that some of these “rules” aren’t written explicitly anywhere. It just depends on how the two people handle it.
Show me where the OP mentions written rules.
No rules at the public library I work at. I’ve dated patrons. I’ve dated co-workers. I’ve dated a patron who later became a co-worker (albeit, in a different building) who later became my wife.
Nope, no rules at all.
At my first place of employment, there were lots of married couples…none with a reporting relationship to each other.
At my second (or third, depending on how you count corporate takeovers), my department admin married our director. She was reassigned to another director.
I make a really good sour cream and chocolate chip coffee cake, and I often took it to the office to share. Even with people I wasn’t dating.
I’m a teacher, and if I consider the kids to be my clients, then dating clients is forbidden. As for dating anyone else, anything goes.
There have been several marriages between co-workers at my company, so dating between co-workers is clearly not forbidden. However, in none of the cases were they between supervisor/subordinate.
At my workplace it’s fine to date peers, and it’s fine to date someone you supervise/are supervised by…until it isn’t (so the “no harassment” qualifer in the poll). Theoretically it’s fine to date clients too, but most of them are only on-site a few days a year so the odds of meeting them and hitting it off are pretty small.
At my wife’s workplace, one senior manager hired his wife to do the accounts -
Yeah, that’s a reallly wise move when she reports to you
Nominated for best non sequitur, SDMB, 2010.
Read the last poll option again.
No rules against dating coworkers. In fact, getting really drunk and doing embarrassing things you regret is somewhat a past time in the industry.
Relationships with customers is often frowned upon though. A few female coworkers have been let go for making a habit of dating wealthy customers, relationship goes really bad, wealthy customers leave and never return and take their business elsewhere. It’d happen to guys too but the relationships usually don’t occur the other way around.
Of course you left out one option: I work at home, alone, so there are no rules about dating coworkers (the cats are not allowed outside).
Two options. Mrs. Devil and I work from home in the same business. I could check off quite a few options (except customers). 
As stated above, no dating people you are in a direct management line with, or may audit. Customers I think would be fine, as long as you aren’t the one handling their file.
And of course, as long as there’s no harassment either way.
Same here - and as a college teacher, we are not even allowed to give a student a ride to the bus stop or anywhere, even in bad weather, etc.
I did have one incident many years ago as a teacher in Los Angeles - also at a college - when one of my students ran into me at a Gay bar and he was a bit very drunk…let’s just say he tried to get to know me better but I was smart enough to avoid that at all costs.
