you work x number of hours each year, then you collect at x age whatever amount . depending on the hours you worked each year, the amount of pension credit you get. part time is roughly half unless you recieved alot more hours than the usual 3-5hr shift. Some part-timers worked full-time for many years before '97. Some regions might differ with their pension setup. This region is all by hours per year = 1-12 credits. What more do you want to know?
