A full 43 percent of American workers “at least sometimes” do their jobs without leaving their homes, according to a Gallup report released Wednesday. That number differed rather starkly from the Bureau of Labor Statistics’ most recent figure—24 percent, as of 2015—but the government agency’s data certainly showed a rise over the past decade, from just below 20 percent in 2007.

“WFH” comes with ample perks, like staying in pajamas, avoiding a long commute and, according to some research, a boost in productivity.

She added that some workers even worried about the rise in their utilities bills—and, conversely, the money they’d saved the company by not using the office’s electricity and water, something they believed should have been factored into their salaries.

“The research overall suggests that telecommuting may be most beneficial in terms of organizational outcomes when it is practiced to a moderate degree,” the study said, adding that “the success of any telecommuting program will depend on aspects of the person (e.g., self-regulation skills), the job (e.g., degree of task interdependence), and the organization (e.g., support from supervisors).”
