work like a mule
To work very intensely for a long or continuous period of time, especially doing something thankless or menial. The boss had us working like mules to get the project ready on time. I worked like a mule the entire summer after high school to earn enough cash to buy my first guitar. I've been out here working like a mule while you sit inside sipping lemonade. Could you maybe lend me a hand?
