AirCanada is the carrier for the mail and other "sensitive" cargo inside Canada and abroad. They have contract obligations. Cargo can still move without check in agents so it hasn't been as big an issue as pilots.
It was actually the Jazz pilots who were threatened with back to work legislation. Jazz is 100% privately owned and its only tie to Air Canada is its capacity purchase agreement. That being said, Air Canada and Jazz aren't the only available operators for carriage of mail or sensitive cargo. BTW, Purolator is owned by Canada Post, Kelowna Flightcraft does their flying, (they used to do FedEx, but that is now done by Max Ward's MorningStar, the work goes back and forth), and is also a union shop. The world will not stop if any one airline shuts down. I remember Air Canada's first, (and only, I think) pilot's strike. I actually walked the picket line with some of them, I worked for the blue team at the time and had already been locked out once and been on strike once. There was no mention of any group being threatened with back to work legislation at any time back then.
The last legal bargaining chip left to employees is suspension of services, or SOS. Working to rule is not a legal option in many cases because it can be deemed as insubordination leading to termination, legally. Not being legally allowed to withdraw services effectively neuters the collective bargaining power of the workers, leaving the employer holding all the aces.
I have no problem with cutting the unions off at the knees with back to work legislation so long as it forces the government into binding 3rd party arbitration.
A wise man once said, "I never knew a company that had a union that didn't deserve one". The unions are not always the bad guys, but yes, sometimes they are. Sometimes they have ludicrous demands, and sometimes they have exceeded their best before date. In the end though, it is much the same as in a court of law, we have our opinions, biases, and prejudice of what equates to justice. In court it is, (or supposed to be) a fight between the Crown and the defendant, we are disinterested parties. The same applies to collective bargaining, the fight is between the employer and employee, and we are disinterested parties, even if we have the misappropriated belief we have a stake in the outcome. Our inconvenience resulting from a labour dispute, that doesn't involve us, pales in comparison to the stakes involved with the real interested parties. I could not, with a clear conscience, advocate that a group be forced to take a 5 year concessionary contract full of dog turds so that I not be inconvenienced for a couple of weeks.
Arbitration is much like going before the judge, you don't know who you're going to get, (though "judge shopping is legal for defendants, not the Crown). Another wise man once said, "the worst negotiated settlement is still better than the best judgment." Problem is, I've seen some pretty bad arbitration decisions, and no one party enters into arbitration lightheartedly.
Yeah, I suppose that the unions would cease to exist without the protection of the gvt... I guess that the unions aren't so necessary afterall considering that they really wouldn't exist in their current form without gvt protection.
Unions have had little to no support in the US since Reagan, but are still a strong force. It is not government protection that makes them exist, although it does make their existance easier, it is worker exploitation that make them exist.
As Cranky alluded to, it is the Rand formula that makes Canadian unions unique. Justice Ivan Rand, of the SCC, handed down his judgment regarding the CAW strike in 1946. In essence, in a closed shop, the union is responsible for all employees, those who are members, and those who are not. To this day you can choose not to join the union in a closed shop but the employer must still deduct dues at source. You, though, can direct where those monies go, to the SPCA, or charity of your choice. The union must still represent you as if you were a member, the only thing denied is enrollment in union sponsored plans such as group life or disability insurance.
As an aside, I do not endorse most parties that support unions, nor do I support unions that donate to parties or causes. It is my money that goes to the union, but it is for union business only. Our union does not give union monies to causes or parties, but does solicit voluntary support for causes it deems worthy. Our union actively supports the Obama administration, (and the NDP, of course), I do not, primarily because this administration is in favour of the UN Small Arms Treaty, which will endevour to disarm all civilians and transfer power of arms to the authorities. But that is a story for a different day. Suffice to say, my freedom of self determination and defense of self is much stronger than my loyalty to collective bargaining.
