So what I am taking away from this is there is a fixed/guaranteed element to the salary which is lower than what they advertise on the website/job advert. The advertised number is based on achieving the target hours for that particular fleet.
My question now is, is there any guarantee that you will be rostered with enough duties to meet the target hours? Seems a bit backward if they are advertising a job with X as a salary based on a target amount but they won't actually roster you for that amount.
