I don't know about Target, but workplace relationships in retail can certainly happen and last. Met my husband at my last job, and know several other couples who met at the same store and are still married. Of course, I know a fair few that crashed and burned as well.
I know of 3 people who have long term relationships with people they met at Target. Over 10 years each and are happily married. That pales in comparison to the amount of failures, dramas, and terms I’ve seen due to relationships in target. I’ll steer far away.
Havent had one but a tl hooked up with a once photo tm and they are still married and have a third kid on the way almost two decades later. Granted their roles at spot have changed drasttically as per how this company is but still a great couple tbh.
