I have worked for organizations with two very different approaches to sharing company information. What I have found is that employees respond favorably to learning about the goals of their organization. This is also a great marketing tool for your employee stock purchase or profit sharing plan. You are not only molding the future leaders of your company, but you are also creating a group of people who can do anything you need them to do. This creates a sense of pride and teamwork, keeping entry-level workers from reaching burnout as quickly.
Cross training is important in creating the team.
Be sure that you give credit where credit is due. Informal feedback can go a long way. Never underestimate the power of a positive word. By the same token, when employees make mistakes, don't reprimand them harshly. Explain how they need to change, but be sure to end your discussion on a positive note.
