Man Friday
A Man Friday is a trusted assistant who helps with many different tasks; the phrase comes from the story of Friday in Daniel Defoe’s Robinson Crusoe. It now sounds old-fashioned and can suggest an unequal relationship between a boss and a servant.
Where it comes from
Friday in the story
Friday appears in Robinson Crusoe as a man Crusoe rescues and names after the day of their meeting. Crusoe treats him as a servant and teaches him to call him master.
After saving Friday from men preparing to kill him, Crusoe gives him food and shelter. Friday later helps Crusoe with work on the island and plans for escape.

The meaning today
The phrase describes a reliable, all-purpose assistant, traditionally a man. Although often meant as praise, it carries the story’s assumptions about service and colonial power.
In Robinson Crusoe, Friday helps build a canoe and proves valuable through his knowledge of nearby lands and peoples. Those practical abilities help explain why his name became a label for a useful assistant.

How to use Man Friday
- Use it for a trusted assistant who handles varied tasks.
- Consider whether its servant-like associations fit the situation.
- Choose trusted assistant when a neutral description would be clearer.
Is Man Friday offensive?
It can be, especially when it reduces someone to a subordinate helper. In Robinson Crusoe, Crusoe names Friday and expects obedience from him. That colonial setting gives the phrase associations that may make it unwelcome, even when the speaker intends praise.
Does Friday mean the day someone works?
No, Friday is the character’s name, not a work schedule. In Robinson Crusoe, Crusoe names him after the day on which he rescues him. Calling someone a Man Friday therefore means a dependable assistant, not someone who works only on Fridays.
