Avoid Love At Work
Keep Away From Infidelity By Avoiding Creating A Work Spouse
You want to stay away from love at the office or setting up a work spouse. This situation, while not immediately damaging, can harm your marriage in the long run.

If your marriage is important to you, you should want to protect it, even against what might seem to be a low-probability issue.
Love at Work Can Lead to Infidelity
I see people who are struggling to repair their marriages after having a "work spouse". The best thing you can do for your marriage is to avoid having a work spouse in the first place.
