Richard,
same as me, if lads are shown how I expect them to look after and use the equipment that I buy for them to use, which is always expensive, if they damage things with lack of care, then they pay for it and they also get a telling off.
If they carry on which they haven't done as yet, then they can find another job and let them put up with there neandrathol ways.
At that point im not interested in employment law and all what comes with it, they wont be working for me again.
Funny thing is, lads who have worked for me in the past always want to come back working for me within 6-12 months, because I am fair with them and want them to use the best equipment, and they then realise I wont put up with it.
