It’s really an eerie feeling to work with someone you had a relationship that ended in a bad note. Office breakups are tougher than normal breakups and things get bit awkward after a sudden breakup with your partner.
But, switching your job is not a good option and you should not put your career at stake for the sake of your bad relationship. I know it’s not an easy task to work with your ex after a breakup but you should try to reduce the discomfort and tension to maintain a healthy professional relationship.
First of all, you should try to keep your personal matters outside the workplace and the negativity of your relationship should not affect your professional reputation. The second thing which you can do is limiting your interaction with your ex. It doesn’t mean you need to avoid important meetings or conferences just to stay away from your ex.
And if you can’t get rid of the memories of your ex, then you should leave that workplace and move to a new city. Start a new journey of your life and career.
