Not against people getting penalties if they have a normal 5 day week and get called in on a weekend or public holiday to do extra.

Against people who work four or five days each week getting extra if any of those days are a weekend, but have their "weekend" during the week.

Also, there are alot of people out there who only want weekend/night work because of those rates, not caring about whether it is a weekend or not.

I used to have staff that whinged if you didn't give them overtime, even if the work wasn't there !
