Steve Jobs would not be where he/she is without the help of Steve Wozniak. The importance of a right-hand man is not just to assist a partner in completing important tasks but to also function as a second in command in leading the team. Of course, Wozniak had a much more important role than that, but you get the point.
A co-manager is basically the right-hand man to a manager. Daily, they are involved in overseeing work operations, tracking performance targets, preparing annual reports, and attending to customer inquiries. Besides that, a co-manager also assists with payroll preparation, facilitating employee training, and helping to develop marketing materials.
Employers require co-managers to have a bachelor's degree relevant to their specialized fields such as engineering, banking, or pharmaceutical. However, in the area of sales, one can become a co-manager with a high school diplom,a provided they can demonstrate at least 2-3 years of relevant work experience. A co-manager earns, on average, $54 per hour.
