The term "grunt works" refers to the monotonous or laborious tasks that are essential but do not require any special skills or creativity. Some synonyms for "grunt works" include menial work, drudgery, routine tasks, grunt labor, housekeeping, busywork, and scut work. All of these words share the same idea that the tasks are necessary but not necessarily exciting or challenging. Often, these tasks are delegated to younger or lower-ranking employees or assigned to support staff. It can be a way to test someone's work ethic or willingness to do whatever it takes to get the job done. However, it is important to recognize the value and importance of these tasks in keeping a business running smoothly.
