I think a major problem affecting the pilot community is a lack of people continuity. Line pilots go to work, they see ground staff on a fleeting basis, they fly with another pilot or crew for a day or a few days. They then go their separate ways and may not see each other for some time. This process is then repeated ad nauseum. As a result, it's highly unlikely that any underlying problems emerge whereas in a 'normal' workplace where colleagues see other other day in and day out, it's easier to spot any difficulties a colleague may be having and address such problems. That mightn't always happen but it's a more probable than with what is essentially a transient workforce. A significant conundrum is how to fix!
