Do married people in workplaces, across all fields, really cheat ?

So, I was traveling in an auto today, and this middle-aged aunty joined midway. She was on the phone, saying something like, "Why won’t you come to meet me? I’m waiting for you. You know we can’t talk once I reach home." It got me thinking—are workplace affairs really that common? Is this kind of thing happening everywhere? If you’ve got any workplace affair stories (funny, messy, or just wild), feel free to share. Curious to know how common this really is!
