I don't know; BLM was pretty successful here at "defunding the police" which was a big joke since they just shuffled the money around, but more importantly it made so many Seattle officers leave that we are told it will take 5-10 years to replace them. Of course those were the bad officers who ate donuts and shirked bike duty because they were too fat 
Here in WA (which has a similar vaxxed rate to Alberta, something around 85%) the unvaxxed are mostly forgotten, they are too small and troublesome to be anyone's constituency except for in the rural areas which don't amount to anything representation-wise. Their loss, since in rural areas state jobs are prized and they lost them to people who are more politically desirable.
The ferry system is still operating at a reduced capacity since they fired about 400 people last October over the vaxx mandate. There's no "scientific" basis to exclude them since the vaxx no longer protects against infection and I am as likely to get the covid from a sleek vaccinated Seattle suburban replacement as from a great hairy Trumpkin I might encounter in the men's room or something. But when I point out the staffing issues could be resolved if they simply rehire the unvaxxed, people just shrug, it's a price we are willing to bear to exact revenge on our political foes I guess. We will see over the summer when the system is choked with tourists whether the governor changes his mind. I think (like in Canada) the presence of a small but visible group of dangerously unemployed agitators that continues to protest in Olympia every weekend is a useful thing to campaign against -- look, I'm protecting you from these people!
It is too bad most restrictions were lifted right when the Ottawa convoy started. General public resentment was building (I saw a lot of regular people join the party and say it was better than winter carnival) and might have been enough to carry you guys along with it, but they played that one very carefully.
So we are in agreement that in a strange way it is too bad that restrictions lifted (I believe most likely in response to what they were seeing in Ottawa and the boarders. Canadians if full rebellion mode may not have been something they were planning on...)
However, your idea of "offer them their jobs back" is probably not going to work. As somebody who nearly lost his job to mandates, I can tell you that I let my manager know that while I appreciated the offer that if I were fired I would be rehired as soon as mandates lifted- that I would not be back. I believe that is an attitude shared my many.
The other problem is that the good and virtuous left is unlikely going to want to start at the bottom of a ferry service for a career. So while it is seen as "worth it" to teach those dirty Trumpkins a lesson- it is shooting society in the foot. If you are at 85% vax rate you have to consider that those who are now past working age are likely 95% vaxed. That means that there are likely 20%+ of the population excluded from the jobs that could make the world run smoother and with more ferries.
I know of several nurses who upon being fired actually moved to the US (I believe most of them went to South Dakota.) I know a number who were working into their retirement who just quit. Our paramedic service is at the breaking point- From early May... "In a tweet on Monday, the HSAA reported that 40 emergency calls in Calgary were waiting for an ambulance to be dispatched on May 3, which prompted union staff to issue a “deep red alert” for the area... Deep red alerts were unheard of until now."
When you fire around 6 - 8 % of your paramedics (and a number resign or retire prior to being fired to work elsewhere or enjoy life) you are going to have problems. These were the "hero's" only 6 months earlier putting with people applauding them. And then they are fired. I would say they lost 12-15% of their most senior staff. And that likely caused others to go on stress leave.
So, I actually laugh when I hear that our health care system is almost broken to the point of people dying in the streets. How fitting that after laughing at the "dirty unvaxxed" it is that attitude that contributes to destroying a once (somewhat functional) health system. I know that ferries are not hospitals. But the same mechanisms are at work. And I doubt that more than a dozen people would return even if offered their old jobs back.
*Oh, did I mention that the government made the generous offer to Alberta health workers that they could return as of March 8? So, 5 days after making the news they offered people their jobs back. I would be shocked if a dozen people returned after being turfed a few months earlier.
