"Annual base salaries for the 117 public works and parks employees who do maintenance and field supervisor jobs range from about $41,000 to $76,000, "

If its true the base salary starts at 41000 dollars, then their hourly rate would be closer to 20 dollars an hour and not 15.    Also I have to ask the question.  What is a base salaried person with the parks department  consistently doing above and beyond their normal garbage collection and grass mowing duties which commands nearly double that of miniumum wage, which by definition their job title would entitle them too?
