At a toy factory
.
.
Worker1: Well, what do I do?
Worker2: Stand at the assembly line.
Worker1: Oh, is this an assembly line?
Worker2: Yes. So, we can assemble, put together, these boxes of building blocks.
Worker1: How do we do that?
Worker2: Watch me, I start by putting the square blocks in the square holes. You’ll soon get the hang of it.
Worker1: Get the hang of it?
Worker2: Get used to doing it. Get on with it.
Worker1: OK. I’ll put some more square blocks in the square holes. Da, da, da, that’s fun.

What does “Get on with it” mean in this dialogue?
