This is where a strong leader's force of will becomes key. If you can't get your worker sheep to obediently fall in line, you will have to use more forceful techniques. Actual physical force against your employees would be ideal, but would probably draw the ire of several government regulatory agencies. Instead, you can bring new visions to your employees: visions of pink slips floating before their eyes and the imminent threat of your foot kicking their sorry asses out the door.
Instill a culture of control via your financial leash. Nothing motivates like the idea of the disappearing paycheck.
