Being an employee is simple: Show up, do what you are told, leave when your shift is done. Simple, not easy.
Employees want to keep their job. That means figuring out what your job is when no one can fully explain it. Sure, they'll explain the tasks involved, but they can't explain every instance when you have to react to things not going as planned. That's the challenge for management, teaching people to think like managers while getting paid by the hour.
It's especially hard to teach because the people who know how to do it can do it without thinking - it's ingrained in their subconscious. As a coach, the only way I've found to enable them to teach others is to get them to bring those activities back into their consciousness, to examine each action and figure out why it works to do it just that way. We usually discover it's because of all the past attempts to do it another way that just didn't work.
That's why good companies spend so much time and effort on training new employees, why they've created procedure manuals and are constantly trying to improve their quality. They are investing in new employees and want to see a return on that investment.
Employees understand that and want to contribute. What they really want is to know what the plan is for the day, to understand what they are expected to accomplish, and to have the right tools to do the job. Make the investment and your return should be better.
