Simply put, businesses need employees. Without employees, there would be no one to take the customers' cash, produce goods, or bust the knees of those who are over-due on their debt.
Attributes for employees are considered to be 1 unless trained beyond that. Employees have an hourly wage of $1 x skill & attribute points. That makes the base wage for an employee $9 per hour with their starting attribute points.
Each employee can produce up to 40 work hours per week. With higher skill levels, employees become more efficient with their skills and can produce more production hours per work hour. (work hours x level = production hours)
Employees can increase skills through training once per week. Training costs $500 for a first skill point, and $1000 x Current level up to level 5. Training takes 8 work hours.
