wonky vectors your name sums you up. not long now, I totally agree anyone doing the job should get the same rate of pay. If management think that an atco2 is worth 50,000 a year then they think all atco2s are worth 50,000 and that is the rate for the job not the pathetic 20 to 30,000 that they get at the beginning of the scale. After all if anything goes wrong you are still the only one responsible, not the very highly paid fifty year old beside you saying "I didn't think that would work..."
