Listen m8tey ... wheres thers blaim ... make a claim ... but obviously its your well being and health which
is No 1 priority ... get legal advice ... lawyers will be fighting for your business and rubbing thier gleefull hands..
I know which I WOULD PICK ... but there are many... so watch for infection get down to your GP or Medical centre
walk in centre to record this injury ... then count to ten and pick a brief ,,, sit back and watch the a/ holes start
twiching where you work ..

I would like to bet that you should have carried out a risk assessment and worn Turtle skin gloves. I've seen this type of thing loads of times. You'll either get a better paid job out of it or ultimately fired !
