"Chopper", in the UK, is a slang term for .... men's bits
. So yes, use of the word in the UK could cause some sniggering but also plenty of scope for some old-fashioned double entendre e.g. "how big's your chopper"? I'd not heard of "pork chopper" - that's just downright funny ... and even more worthy of a good chortle!
Anyway, back to the original question. If your employer is willing to pay for a helicopter rating (and your use of the word "rating" makes me think you might be FAA), he must have some idea how he's going to use your qualification. As soon as you pass the skill test and exams, you can be a commercial helicopter pilot, flying on your own.
