Wages have been stagnant for most jobs over the past decade. So if you're hoping to increase your salary significantly, your best option is to try to make the leap into management. Indeed, the average manager's salary is $108,570 -- or more than double the average salary of U.S. workers, according to the Bureau of Labor Statistics. So where are the opportunities? Who is hiring?

Here are the 10 employers with most management positions open this week:

Manager Review: "Petco is a very collaborative culture and the people who work here are great. I get to bring my dog to work and wear casual jeans all summer long.
