Hi Who:
I think I was misquoted a bit... let me repost:
In general, "external" forces designed to disrupt an affair usually have the opposite effect---they tend to push the affair couple together.
This was with regard to a specific instance as well (the affair had been public for at least a year, and there was question as to whether to make a run to the CEO to tattle).
Exposure is all about ending the secrecy of an affair. It lets your spouse know that YOU KNOW! It starts the clock. Affairs thrive in secrecy---there's an adrenelin rush that you get when you sneak around doing stuff you shouldn't. That's part of the addictive nature of an affair.
So, how to expose? It's a situational decision (as well as a moral decision for some with regard to OP's spouses). There are a few guidelines for exposure:
1. You're doing it to end the secrecy---not as punishment.
2. You're doing it do set up a chance at recovery.
3. Once you do "it", you can't take it back.
A measured, tiered exposure pattern was the method Steve H used with me, and I believe it's the one that he advises most of his clients with. To give you my case---my wife was having an affair (not workplace), and our children were 7 and 3 at the time.
1. First exposure---to her. And only her.
2. Second exposure---her sister. That was about 1 month into a Plan A.
3. Third exposure---parents and some close friends, about 6 months in, as I was transitioning to Plan B. Kid's were not informed.
These are measured responses. While some believe that you should shout it from the trees immediately after you find out---there's scant evidence that this approach ends an affair any quicker, and evidence (ancedotal) to the contrary that it leads to successful recoveries.
Keep those guidelines in mind. If I had a hypothetical situation where my spouse was having a workplace affair---I'd expose to her first. Plan A and POJA with her to change jobs. If this was unsuccessful, I would then probably expose the affair to her supervisor(s) and HR at work.
I hope that helps---you're not 'incorrect' with regards to your thought on exposing a workplace affair---but the application on the other thread was inappropriate.
