My sister got married to a guy she wroked with. They had been going out for several years without anyone even knowing about it. They are both older, my sister has a 21 yo son... Anyway, their company policy prohibitted dating but they were very careful and discrete, knowing no one would know and preparing to quit if need be. They never did anything during working hours of any kind to show they were involved.
My sister did quit when they announced to the company they were getting married and she was leaving. He was vice president and she was some other thing in charge of the company. Pretty big place in a few states. She does consulting work for them sometimes. There was no hard feelings. My sister was there for 25+ years and the husband was there 20+ I don't know exactly.
That's all I have to say about that.
