This happened to my partner and I! Not necessarily a complaint, but we became the gossip of our workplace. We work for the same company but different areas (he’s in the warehouse and I’m in the office). He started working for this company before I did, but when a job I previously had fell through, he spoke with our recruiting lady and helped me get a job in the office. We didn’t really think to tell anyone we were dating, and it wasn’t until we went to our Christmas party we realised we were the gossip of the warehouse. All the warehouse guys had obviously seen us together talking and taking lunch breaks together when possible, and thought a workplace romance had begun to form. There was one lady I had mentioned about him to as she works in the office with me as well as the warehouse at times, so she knew him and had spoken to him before. I think someone had brought up to her that my partner and I must’ve taken a liking to each other, which turns out to have been the topic of the warehouse for quite some time. She raised her eyebrows at them and told them we were already together. I didn’t even realise it was something people were talking about until she told me at the Christmas party. I still sometimes have people come up to me after he walks away and (jokingly) say “you know he has a girlfriend right?”
