“ they got married, have a family and been together 25 years”.
My parents also met at work and stayed married till my fathers death. But once they got married one was required to quit (early 1950’s). However, becoming involved with a co-worker is not a good idea anymore.
What's good is good. It doesn't change.
The fact is that now 90% or more of non-family opposite sex contact occurs in the work environment.
If you care about people forming families and having children (as opposed to, as one poster put it, "thinking with their gonads"), then this new pattern of meeting potential spouses has to be accommodated.
