In one sentence, describe what the following article is about:

Before even engaging in activity to find out if your coworker has a crush on you, you need to figure out what your company’s policies are regarding workplace romances. This is important even if you don’t want a relationship, because even the rumor of two people being involved could cause problems.  Check your employee handbook, if you have one, for policies on workplace relationships. Talk to a human resource representative, if you can’t find information elsewhere. Tell your superiors if you begin a formal, mutually-recognized relationship. When trying to find out if your coworker has a crush, you need to make sure that you avoid any conversation or activity that may be construed as sexual harassment. This is a very tough thing to do, as different people may be sensitive to this subject and could identify what you think is a harmless comment as something much more.  Never make a blatantly sexual or romantic comment to anyone you are not in a formal, mutually-recognized relationship with. Don’t touch other employees unless invited to do so, and never do so at work in a sexual or romantic way even if you are in a mutually-recognized relationship. If you think someone has a crush on you, and you’re uncomfortable letting them know you’re not interested, consider contacting human resources. If someone makes unwanted advances toward you despite your signals to stop, contact management or human resources immediately. Perhaps the most important thing to do when trying to determine if a coworker has a crush on you, is to avoid making assumptions. By making assumptions, you'll jump to conclusions about things without being properly informed. When you do this, you may do something or say something that could get you into trouble or hurt someone else’s feelings.  Make sure you always have the correct information when making a decision about what to do. Don’t treat someone differently because you think they have a crush on you. Don’t expect a date, sexual favors, or anything of the sort from someone you think has a crush on you.

Summary:
Learn about your company’s policies regarding relationships in the office. Avoid anything that could be construed as sexual harassment. Don't make assumptions.
