In white collar office environments where employees tend to care about their longevity at the employer, I would not recommend trying to form any sort of romantic relationship with a co-worker. It's a really bad idea.
Bad Things That Could Happen
- She could reject your advances and then you're stuck seeing her at work day in and day out. Even with more work at home lately due to pandemic, you might still have to have phone calls or video conferences with her. That's an unpleasant reminder. I hit on some woman at my gym and she rejected me and I had to see her for a long time after the rejection. That wasn't pleasant, but at least it didn't affect my career or mood at work.
- She could whine to HR about you. This can happen just based on an approach, but could also happen at any point in a romantic relationship. HR usually won't take your side. If this happens, you'll need to find a new job.
- Even if an approach is successful and results in a sex and/or a relationship, eventually things will sour. You won't likely seeing her at work. You'll probably need to find a new job. For most business professional for most of the past 15 years, the job market has been lackluster due to recession or lackluster recession recoveries. Finding a new job is a pain.
The only time that you can date a co-worker is if you are both working some low wage, temporary sort of job where neither one of you cares about longevity at the organization or your career. Store level retail is a common case of this, but there are some other situations.
@Rocnavy: You are 33. Why interested in a single mom? Plenty of 24-32 year olds are childless. A single mom at work is a really bad idea.
I'm fortunate that my current job is mostly male. The few women in the organization are not physically appealing to me.
In some past jobs, there were some pretty women. One job where I had a multi year tenure had a couple of "cute" women but no one "hot". I wouldn't mess around at work for merely "cute". The best looking of the "cute" women and I would have been incompatible anyway. There were similar stories with other "cute" women at that job. Mainly that job tended to have highly educated (more than a BA/BS degree), highly career oriented women, which isn't what I wanted in a girlfriend.
