Work smarter, not harder, as they say, and it's smarter to work less and make more.

Some U.S. cities will give you more bang for your paycheck buck, according to RewardExpert, a site that helps people maximize credit card rewards. They analyzed data from the Bureau of Labor Statistics on average hours worked per week, wages and weekly earnings to determine which U.S. cities have the best-compensated workers with relatively shorter work weeks.

Out of 387 metro areas, these cities ranked in the top where people work fewer, better-compensated hours. These are the cities where people work the least and earn the most.
