Why do companies have casuals.
To meet the demands when loads are heavey and not have them sitting around getting paid when times are slow.
Thats the economical side,but these days how many jobs you see where its permanent casual for 6 or so months with maybe full time after that.
You may get someone who is never there ,doesnt work enough ,doesnt get on with anyone etc etc.
Now hire him fulltime from the start and then try and sack them------unfair dismisal--discrimination etc etc
Lot easier to start with casuals and if they meet the grade move them onto full time when a position becomes available..Less problems.
But why take a job then whinge about it ,unless the dole office made you do it.
