It sounds like you're not a very good manager, unfortunately. One of the most important things a manager does is understand how to communicate productively with each of their reports. If you have reports whom you believe cannot "follow simple instructions", your first response should be to re-evaluate the way that you provide guidance to that person, not to decide that they're "an insubordinate ass".
You come across as a know-it-all and patronizing in the above two comments alone. May be you can start by recognizing that developers are not your extra sets of arms to code stuff. You should limit your self to clearly communicating objectives and measuring them rather than guiding devs (micro-managing ?) at every step.
