What does 'get on with someone' mean?

Two main meanings:

1. Have a good relationship: "Do you get on with your boss?" = Do you have a good relationship with your boss?
"We've always got on really well."
"They don't get on — there's tension whenever they're in the same room."

2. Continue with a task: "I need to get on with this report." = I need to continue working on this.
"Stop distracting me and let me get on with it."

Telling them apart: If there's a person as the object, it's about the relationship. If there's a task as the object (or "it"), it's about continuing.

British vs American: Meaning 1 is distinctly British. Americans say "get along with" — "Do you get along with your boss?" Both meanings 1 and 2 are well understood in American English but "get on with" sounds British.
