In British Airways pilot managers used to be referred to as 'Bidline Refugees'.
In those days seniority = lifestyle = money. If you did not have the seniority to write a reasonable roster then being full-time and junior sucked. OTOH being a junior pilot manager means you will pick yourself 1-3 trips a month, (usually departing on a Monday) and spend every weekend at home with the kids plus 17.5% uplift on current salary. What's not to like! To be fair that variety of managers were not very ambitious but resented being told to stay to 5pm every evening so the department looked like it was busy. Office life in a corporation!
