I work in a very similair sector and public liability is an important factor for exactly this reason, accidents happen! If you want progress on this one just go to the top of the food chain, pretty useless talking to the poor saps on 8 an hour, they know nothing nor do they care. Count your lucky stars u r ok and take a visit to ur gp for a check up. Glad u still able to talk to us about it mate! Ahoy.
