People and change (the ones that run the company really) have no ATC experience. The only managers that are ATC or ex ATC are generally ALM's, checkies, UTS and SDL's.
There are hundreds of manager level positions within the company. To presume they all came from a core base of about 900 ATC's is interesting.
I have friends in the RAAF, when they went to OTS they couldn't get leave to attend a wedding in another state. I suppose another example of inflexibility and not the best way to do things.
If you don't want to do shift work, then ATC is probably not the job for you. Part of that shift work is taking leave when its available. Sure you might be able to get short term ad hoc leave in the field, and we have things like bereavement leave like most others but it boils down to you organising a swap with someone else.
Just curious Blippy, do you currently or previously work for ASA?
