You certainly would call yourself a Journeyman in the US, as in Journeyman Wiremen. It's all over the IBEW Journal. You might also say you are a Master electrician if you've passed the Master's test. This distinction does come up on the job.
If you are an apprentice, you might call the electrician you are working under your Mechanic.
Sometimes you might "pull a nooner" (leave at lunch), "get some gook" (skim some copper wire off of the job to resell), or even "drag up" (quit), and "go get your money" (collect your wages up until the last moment you've worked).
You might need a "pair of dykes" (small diagonal cutters for snipping small wires), but your company may have realized how offensive the term is and banned its use, especially if there are women on the job.
