Depends what type you employ, I work in this industry and the English are exactly as you described, but the polish, now that's a different thing altogether.
You see, english moan all the time that foreign people take all the work, yet at the end of the day from my experience and probably Jillsaints aswell, the english are unreliable yet the polish, somalians, zimbabwians, eritreans etc, will do the work with no problems.
If I get infracted for the above statement then meh, truth hurts.
p.s. I know it doesn't include all english people.
