at work vs. on duty

[Elicene]

Please, I want an answer regarding these two words that you send to me.

at work and on duty, what are difference between them ?

[Tofu]

at work
at the place where you work
- If he’s not at home, he must still be at work.

on duty
working at that moment
- The nurse on duty called for a doctor.

I need more details.

What is the difference between them?

As Tofu has noted, "at work" generally applies to location. "On duty" applies to the act of working and not to location.

The man is at work. - He is physically at his place of employment.
Do not bother me while I am on duty. - Do not bother me while I am working.

This distinction is blurred with certain occupations. If a police officer is at work, he may well be driving around. A sanitation worker might, as well.

"At work" can also apply to the act of working, however.

He is hard at work. - He is working hard.
Do not bother me. I am at work on this proposal. - I am working on a proposal.

Thank you, Mordant.



Is the rescue team not at work but on duty?

[Mordant]

Tofu, the rescue team is both at work and also on duty. Because their work requires consistent travel, we would not say they were at work only when they were at their place of employment. Of course, they certainly fit the definition of "at work" that is the same as "on duty." As I said, the "location vs. act" distinction is blurry anyway with professions that require constant movement.

The following dialogue takes place between the daughter of a fireman and the child's mother. It happens as dad is rescuing a cat from a tree.

A: Mom, where is daddy?
B: He's at work, honey.

Thank you, Mordant.



The nurses and the doctor are on duty, aren't they? They are taking care of the patient.

[Mordant]

They most certainly are.

Thank you, Mordant. I hope that our posts are of help to Elicene.
