I was on 4% for the first 5yrs, 6% for the next 5yrs and now on 8% and that is as far as it goes.
When my present boss took over the contract that we worked on with another company, he agreed to honour our time served already, luckily for us, not many bosses like that over here.
He holds our vacation pay back until we want it, I’ve got 16mths built up and it’s a tidy sum now.
Also, we can take as much time off as we want unpaid.
I once read that 4%=1week, 6%=2weeks & 8%=3weeks, or the equivalent of.
