base pay + (base pay x 3%) + a + b + c = x
base pay + (base pay x 5%) = x
base pay + (base pay x 3%) = x - a + b + c
base pay = x - (base pay x 3%) - a - b - c

I can live with the wage part, how I can do my job better is another matter and I don't think boots up managers' quoits is a valid EBA claim.
