The primary stakeholders in such companies are the absolute owners, and the organization is generally hypothecated. The internal policy is to keep the employees hungry and wanting. There are very few, though, these days, and those disappear as soon as the economy takes a trend change. Such organizations are not scalable and have their fate sealed for a shorter stint.
Another more important reason is that the employees behave like "Animals" by choice. This syndrome is more rampant across industries. Chaotic attitude, lack of planning, insecure reactions, always nodding heads to the bosses without analyzing and questioning, focused on temporary benefits and not on growth, not worried about the organization, self-focused, afraid to speak before the senior management assuming job threat, complacent on acquiring new skills, risk-averse and trying to be risk-proofed, self-blinded to the changes in the world and industry trends, permanent job more important than skills/capabilities are some of the symptoms in general.
Many organizations have policies to manage and control such resources who find it a bit difficult to be human. For all the confident "Human" resources who can differentiate, there are separate policies or exceptions which are mutually beneficial, to both the organization as well as the "Human" Resource.
Hope this helps.
