drudgery
tedious work / hard labor / monotony
Noun
This term describes the oppressive feeling of labor that lacks intellectual stimulation or creative reward. It emphasizes the grinding, monotonous nature of a task rather than just the difficulty of the work itself. It is frequently used to describe low-status roles or the necessary but tedious parts of a larger project. As an uncountable noun, drudgery does not have a plural form and cannot be counted with numbers. To refer to a specific instance of such work, one must use partitive constructions such as a piece of drudgery or a period of drudgery.
