How should you deal with a breakup when you work together?

After the break-up, keep is professional. Just being 'friends' can make it very complicated. Make sure you both understand that you will still be around each other on a daily basis, and get comfortable with that.

You could always confront them about it and set some ground rules on how to proceed with a proffesional relationship after a personal one has ended

when you work together & see them oftenly, then you don't have to run from the situation. Be BRAVE and face it, act as if they are your colleague.Also you can think this way, think of you at their place and then feel what they feel if you do something and try to be confident , strong and Happy.

Talk to the person. There have to be ground rules set up. You both have to be mature and talk and make a plan out of it. It may not be something easy for most people, since there is a lot of unwanted and unavoidable interaction. But, there is always a way. One of them would be to spend time with other colleagues. Don't run away from the problem, face it and work to make sure it doesn't affect you anymore. Talk to someone and let it out, whether it be a colleague or a peer. Good Luck and take care!

If you try to keep it a work atmosphere, and not a social atmosphere,and not speak of personal things. Try setting boundaries and stick to them

meditate. see yourself, surround yourself with positive people and have time with your friends. this might help you divert your attention. :)

Try not to bump into each other much. Focus on your work more than your surrounding. Make sure to have lunch with your other office mates rather than your ex.

If you're struggling with a stressful situation at work make sure you talk to your HR person - they can help resolve conflicts and make sure protocols are in place to ensure a healthy work environment for you and your coworkers.

It's a toughie. It takes a lot of strength from both parties to accept the personal life is different to the professional.

I guess engaging yourself in your work. However its very difficult because when others will pass comment to anyone of you. It will affect both.
