I’m on my phone so I won’t be easily able to quote specific posts, but a few thoughts. Caveat- I’m not taking a particular position on CAF unionization.
The closest relevant comparator in Canada is probably the recent unionization of the RCMP a couple summers ago. That took many years of legal action to win the right to unionize. Absent a voluntary legislative change, CAF would likewise need to see a successful legal challenge of the statutory barriers to unionizing.
RCMP now comes under (but has its own part within) the Federal Public Service Labour Relations Act.
In both RCMP and Public Service, “officers” cannot participate in the union. RCMP have commissioned officers. Presumably CAF would face the same restriction.
While CAF pay has been linked to public sector, unionizing can change that. RCMP got a 23% raise- granted, they have comparators in the form of other police services.
VAC and pension benefits are not subject to collective bargaining- this is a legislative provision.
RCMP collective agreement has a national security provision.
Union doesn’t trump operational needs. The big things are pay and comp, grievances related to the collective agreement, health and safety, etc. Management still has the right to manage. More a matter of making sure members aren’t worked continuously past the point of safety, and that they’re fairly compensated for working extra hours.
Plenty of emergency services unions have no right to strike. No need to fear CAF would be able to use labour disruptions.
Unions can and sometimes do advocate for retirees, but from what I’ve seen this seldom has teeth. Most grievance provisions expire when you cease being an employee.
