When we work overtime, it means that we are putting in extra hours at the workplace beyond our regular schedule. But sometimes, we may want to express the same thing in different ways. Some synonyms for working overtime include putting in extra hours, working additional time, staying late, pulling a late shift and burning the midnight oil. These expressions convey the same idea that an individual is dedicating more time and effort to their job beyond the usual work hours. It is essential to plan your work schedule effectively so that you can have a work-life balance and not overwork yourself. Otherwise, you may end up feeling burned out and unproductive.
