The easiest way would be to ask your union steward at work, he should have a copy of the current contract, which will outline the progression for wage increases. You could also contact your local and request they send you a contract book (always good to have). In my book starting wage is 70% of top wage, upon seniority (30 days) 75%, seniority date +1year 80%, seniority date +18 months 90%, seniority date +2years top rate. depending on where in the country you work will determine top rate on which to base your figures. Hope that helps.
