Striking Post?

From Canada Post:
"Public Advisory from Canada Post Regarding a Potential Work Disruption"

Labour negotiations between Canada Post and the Canadian Union of Postal Workers (CUPW) continue.  Talks have been ongoing since late 2015, and the parties are now in the final stretch. No legal work disruption can occur until July 2, 2016. Details of the offers are highlighted in the background section below.  While there is still time to reach new agreements, a legal work disruption could occur as early as July 2, 2016. We understand the impact a work disruption would have on customers and are therefore doing everything possible to reach a negotiated settlement quickly. While a labour disruption remains a possibility, we are asking customers to take precautions. In the event of a labour disruption, Canada Post will not operate. Mail and parcels will not be delivered, and no new items will be accepted. Any mail and parcels within the postal system during a work disruption will be secured and delivered as quickly as possible once operations resume.As a result, many organizations have already communicated their contingency plans to their customers.  To ensure delivery through Canada Post prior to a possible work disruption, customers are encouraged to send any items as described below:

Product (within Canada)	Last day to ensure delivery by June 30
Expedited Parcel (Regional)	June 27
Expedited Parcel (Local)	June 29
Xpresspost (National & Regional)	June 28
Xpresspost (Local)	June 29
Priority (National, Regional & Local)	June 29

^ I can not understand how this is legal and allowed to happen. When the mail service of a country stops then it only shows the ineffectiveness of the country as a whole  - the same way shutting-down the entire government does. People, in general, have become too self-righteous in recent years (probably from the parenting trend of telling everyone they are a winner and their are no losers. With that arrogance comes this belief that they deserve the world and are entitled to everything without the need to work or take responsibility. I think that has led to many strikes around the world. These are "abusive" strikes in that they aren't for basic civil rights, but come from a "I want it all and I want it now" mentality. There are real people suffering throughout the world that could only dream about what we in the industrialized countries have and yet all you see and hear about from us is crying for more and striking or demonstrating if it is not automatically given to us. Gone are the days of people doing an honest days work for an honest day's pay. It has been replaced by lazy people who don't want to work, but still want all the benefits. ^
