Cách sử dụng
The expression "a cog in the machine/wheel" is used to describe a person who is considered to be only a small and unimportant part of a larger system, process or organization. It implies that the individual has little control or influence over the overall outcome and is simply carrying out a routine, mechanical task. This expression is often used in a negative way, to suggest that the person's work is monotonous or unfulfilling and lacks creativity or autonomy. For example, "I feel like just another cog in the machine at my job, doing the same thing every day without any recognition or input."
