Would you tell me whether I am right with my interpretation of the expressions in bold in the following sentences?
She was on the trot from early morning until late at night. (Mansfield’s “In a German Pension”)
I’m on the trot all morning and I’m exhausted.
I've been on the trot all day. (coll)
to be on the trot = to be busy
Thank you for your efforts
