Seniority is only a benefit to the Employer, NOT the employee. It creates a captive workforce-which can never benefit anyone but the employer. Although it has some benefits e.g. transparency the negatives definitely outweigh the positives especially regarding Terms and Conditions. How many other 'professions' are promoted purely on seniority.?? Another stupidity of the industry, especially in Australia is pay based on weight. Given that the larger aircraft generally do less challenging flying than the smaller ones fleet pay is a much more logical way to go. It stops people changing types purely for monetary value. A commander on a 330/340/777/787/744/380 have EQUAL responsibility and should receive equal remuneration. Pay should be narrow-body and wide-body. Before anyone accuses me of personal bias I have zero interest in returning to an Australian airline, these are merely my observations from outside the petrie dish!.
