Why Are We Still Killing Our Workers?
4 staff = at least $800,000. Where would you put them. (4 people is getting close to the sweet spot where you need a fifth person to cover the leave absences of the other four - so lets call is a $m)
Worksafe fines go into the consolidated fund (like all the other fines) not to worksafe. So all bigger fines would do is theoretically reduce the overall tax burden. Perhaps an increase in the OSH levy is what you are looking for. (I wouldn't be keen on that because that means I pay more and get nothing for it)
ACC is very generous. If you die reasonable funeral costs are covered and if you have dependants they get cash for quite some time.If you don't die you get 80% of your lost earnings plus a truck load thrown at you to get you rehabilitated.
We traded this generous compensation for the right to sue. When you introduce the right to sue the only winners are lawyers. Within our legislation part of an OSH "Fine" can be paid to the victim.
Fines ought to be proportional to ones ability to pay. Big profitable companies = big fine. Low paid worker = small fine. Either way it is to hurt. Its called a consequence.
