A results-only work environment is an approach to company culture in which employees are rewarded for their work output, not the number of hours worked or their presence in the office. At a ROWE company, employees have a lot of autonomy over when, where, and how they work as long as they meet their goals. Employees also manage themselves rather than everything being controlled by supervisors.
The ROWE approach is more radical than flexible hours, which still requires employees to work a certain number of hours per week. It also doesn’t require employees to report to an office a certain number of days per week; in a ROWE company, work is something you do, not a place you go.
