She and I really get along and we have a blast when we are together. I'd really like to ask her out on a date and see what develops, but I'm worried that with me being her boss this could get complicated. Between an employer and employee or supervisor and supervisee, workplace romance is a recipe for disaster. The two primary hazards are the potential for conflict of interest and sexual harassment.
Sexual harassment is defined as unwelcome sexual conduct that creates a hostile work environment.
Because this is often based on subjective perception and interpretation, the fear of being charged with sexual harassment can be highly disruptive to your work environment. These concerns will be magnified if you do enter into a relationship which subsequently fails. Considering the potential legal complications and the tension that will likely be introduced into your workplace regardless of whether the relationship succeeds, I suggest you seek romance elsewhere and hold on to your great working relationship.
