CN Rail signal union issues 72-hour strike notice

No strike necessary, unless it is to highlight unsafe practices and shortfalls of the Canadian Transportation Agency, as it pertains, in this case, to the lack of actual licensing of electricians in the CN Rail Signal Union. Aside from PEI, Quebec, and Manitoba, who require the licensing, the requirement is only voluntary in Newfoundland and Labrador, Nova Scotia, New Brunswick,  Ontario, BC, and Yukon.
Yet, here we are facing yet another railway strike,…CN Rail Signal Union.
Why is this acceptable to the Canadian Transportation Agency, and why would you be entertaining a wage increase to include those who are not fully licensed? 
For the safety of Canadians, travelling, or in their hometowns, we are fed up with the lackadaisical ways these shortcuts are permitted, adding to the unsafe and, often deadly, outcomes.We are sick of those making $65-$80/hour, striking for more pay, while they are earning approximately  $45-$60/hour more than many struggling Canadians, and $55-$70/hour more than those not thriving on Ontario Disability Support Program or government pensions. When strikes like these occur, your actions force the increase in costs, whether you win or not. Ongoing price increases land in the empty pockets of consumers. While those on the bottom rung barely hang on, you step over us on your way up. The only way to survive morally is to stop thinking just of yourselves. While you might have to give up a sport or activity, a holiday, or postpone a new car, we are giving up food, heat, electricity, and hope.
