Yes, it's generally considered polite and respectful to address your coworker by their name if they make an effort to call you by your name. Using someone's name in conversation helps create a friendly and positive atmosphere in the workplace and can contribute to a more comfortable working relationship.
By addressing your coworker by her name, you demonstrate that you acknowledge her as an individual and value the effort she puts into remembering and using your name. It can also help foster better communication and rapport between the two of you.
If you're unsure about using her name or if you've had a specific reason for not doing so in the past, consider making an effort to start doing it now. It's never too late to improve workplace interactions and show respect for your colleagues. Just remember to do it sincerely and without any hidden motives. Being respectful and using names when appropriate is a small but meaningful way to create a more pleasant work environment for everyone involved.
