Peggy Olson, Walter White, Leslie Knope And More: TV's Hardest Workers

Labor Day means three-day weekends, barbecues, and soaking up summer's final days. But let's not forget the main purpose of this early September day: celebrating workers everywhere.

At HuffPost TV, we took at look at the hard-working characters on the small screen.

From Peggy Olson's (Elisabeth Moss) climb to the top of Sterling Cooper Draper Pryce on "Mad Men" to Leslie Knope's refusal to give up on her campaign for city council on "Parks and Recreation," check our slideshow of TV's hardest workers.
