WASHINGTON (AP) — Exploring the cosmos makes for happy employees, federal workers like to work from home like everyone else, and an agency that has struggled with low morale is showing improvement.

Those are some of the highlights of a survey released Monday of more than a million federal workers.

In a city that revolves around the federal government, the annual Best Places to Work survey is a closely watched annual event worthy of bragging rights — provided you’re one of the agencies such as NASA or the Government Accountability Office who topped the survey.

The survey uses information from the Office of Personnel Management’s Federal Employee Viewpoint Survey and is produced by the Partnership for Public Service and the Boston Consulting Group.

It covers 532 federal agencies including 17 large agencies, 26 midsize agencies, 30 small agencies and 459 subcomponents. The rankings first came out in 2003, and agencies that do well are known to post the results on their websites.
