There are lots of reasons why people work extra hours. In some jobs, it’s the only way to cover the workload. In others, the pay is poor, so people need to work extra time. And in others still, working back late or on weekends is encouraged and rewarded, explicitly and implicitly.
Those employees who do the extra hours, willingly and without complaint, are seen as hungry and ambitious. A view expressed in some workplaces is simply “that’s what everyone does”.
