Every business has to consider not just what the wages are, but also something called the annual employee burden. At $13 per hour times 52 weeks, gross wages are $27,040. The employee burden, however, includes insurance, sick days, holidays, vacations, training days, company meetings, and benefits that cost the company but do not financially add to the bottom line. At $13 per hour, the employee burden can more than double the hourly rate. A $13 per hour employee can cost the company around $45,000, a $15 per hour employee can cost the company over $54,000. This can be disastrous in a recession year because they have to be paid regardless of the tax income.
I think it's better to pay government employees a base wage plus a commission based upon tax revenues. That way in a great year, the employees make great money; and in a recession year the employees have to cut back just like the rest of us out here in the business world.
