I'm a former military wife. So I was involved in protecting national security while changing diapers and generally being viewed by the planet as a big fat nothing homemaker. "Loose lips sink ships."
So I viewed my corporate job as merely a day job of no special importance, thus I was not sucked into the cult-like atmosphere of the place. I imagine I would be equally resistant to the cult-like atmosphere at a tech company.
She waited 18 months to say publicly what she thought about it. She's still quite young and 18 months is not a lot of time in the grand scheme of things.
I'm 53. I had an affair in my twenties. I then read as much research as I could get my hands on.
Some common themes:
People frequently are unfaithful while physically separated from their spouse. It's a common feeling that it somehow doesn't count if you are far apart. In fact, some people use that stance as justification to have an ongoing long distance affair.
Affairs are common in stressful situations. When things are overwhelming, humans have a weird habit of reaching for a smidgen of distraction and comfort amid the chaos.
Although popular opinion is that affairs ruin relationships, cause and effect almost always runs the other direction: Affairs don't kill relationships. Instead, relationships in their death throes foster affairs.
I generally consider 18 months to not be a whole lot of time to gain perspective on international and cross cultural experiences. Cultures and nation's tend to be far older than the individuals in them and it can take quite a long time to digest the intersection where two such things meet in one person's life and, unfortunately, all too often grind on that specific individual.
The phrase "cult-like atmosphere" of corporations is meaningful too. Having lived in different national/regional/organizational cultures, I'd agree that there's a significant correspondence between culture and cult.
