From memory about 50% of those employed at Liverpool, in a maintenance capacity, actually work!
Sorry but I couldn't resist getting that in.
If you are a craft apprentice and are any good at sheet metal work, you might want to try going on the circuit as a contractor before you decide where you want to go and what you want to do. Getting your B1 is not easy and I know a few people who have bailed out once they've seen what was involved.
Just a thought for you to consider.
