1. Do: Keep your work separate from personal issues
It is very difficult to separate office issues from personal ones when both the partners are working in the same organisation. It takes two mature people to understand this and not let emotions affect your work.
2. Don't: Broadcast your relationship
Even though you might not like it, it's best to keep quiet for as long as you can and maintain a professional relationship at work. Believe it or not you will become the topic of discussion in the office if you're not careful.
3. Do: Be sure it ends amicably
When you breakup, it can be very dirty if things are not handled properly. Since both of you will be in the same workplace. You will be seeing each other regularly and it can become very uncomfortable.
4. Don't: Mix business with pleasure
Don't misuse your relationship to get ahead professionally. You don't want to be tagged as the 'office slut'. For as much as you may try to keep an office romance under wraps, word does get around. And if things don't work out, unfortunately the tag will still remain.
5. Do: Date someone of equal status
One cannot deny the fact that power dynamics exist in the workplace. People are bound to talk if you get involved with a superior. And if you get a raise or a promotion, the only thing that will come to their mind will be that you were favored more than the other for certain
6. Don't: Avoid making out in office premises
Public display of affection in office is a no-no. Not only does it blacklist you as unprofessional, it also can be very embarrassing.
