The 5 Principles (Quality, Responsibility, Mutuality, Efficiency, Freedom) are posted very visibly at every Mars site, in every conference room. The problem is that you constantly see people preaching about them while breaking them in the same breath. One prime example is something called a punctuality bonus. At Mars every associate punches in at a time clock regardless of position. If you are a minute late you lose your punctuality bonus for the day, which means you lose 10% of that days salary. The problem is that some members of management never punch a clock, they override it, which is fine except in the same breath they will tell you that they have to do it just like everyone else. This is one example of the hypocrisy that pervades the business.
Like any other company you have good people and bad, the thing is that in the span of my 25 year career I've never seen so many bad people in management, getting promoted through the ranks while good people stagnate in low paid jobs, or get backstabbed out of the company.
I personally witnessed a scenario where product went through development and made it's way to the retail shelf of one division with a retail price point before the plant management had determined production cost or assigned a wholesale price. Three people involved - the one who discovered the error, and the two who committed it. Guess which two were promoted and which one left the company.
Associates are either grossly underpaid, or grossly overpaid. This means that in many cases you can't attract good talent unless you catch them in a time of desperation. Overpaid associates are generally ones who landed in the right place and either manage to master the game of Mars politics through stepping on the necks of their peers or playing the game of not caring about what's best for the company when it conflicts with what's best for them. The Talent Management System encourages this practice leading to situations where if something is good for Mars but isn't on an associates objectives, it's ignored regardless of whether it impacts a departments budget or not.
