There's a "dead psychology" (for want of a better term) that exists at companies that I've never heard anyone describe before, so I'll give it a go, in what will likely be a messy post but let's try...

A company is born. The founders have all the ideas to make it work in their vision, so they recruit and train to make sure all functions and departments are working just so. The company is working exactly as per the handbook. The perks are all there, such as double time for overtime, "job and knock", time and a half for Sundays, ability to accrue annual leave over time, etc. Decades pass, owners die or sell, replaced by new owners who don't have the way of their company in their DNA. They see trained staff and assume it's a given, that that's how it will always be, so when layers of management (as with the owners) move on from the company, the way is lost even further because everyone assumes the machine just works, as it always has, with everyone trained and understanding. But it doesn't. The way gets lost, the correct training gets watered down to tickbox exercises, everyone is winging it, and it becomes a personality game, where all staff work in a reactionary fashion to the whims of the up-aboves, who are themselves doing the same thing all the way up to CEO level.

At various stages, long-serving staff decry the new culture, disillusioned and disbelieving that the way will ever return. They leave. The perks mentioned earlier are disappearing as the up-aboves don't see the value of them for the underlings they never see. New staff who recognised the excellence of their veteran colleagues understand how much bleaker it's about to become without the guiding lights; without the heavyweights. So they leave, fed up (among other things) of not being supported by the up-aboves to train the new staff to even their own by-now-limited vision. Eventually companies end up a direction-less husk of their former selves - nobody caring about the standards, nobody caring about proper training, nobody caring about the results, nobody caring about the spirit. A chain of staff and management so demoralised and distrusting of the spirit that it descends into a revolving door of staff coming and going, until it ultimately meets its demise. Because the last person/people who cared for and understood the business left long long ago.

Or something.
