Bombardier got good deal on strike 18 days on strike that's about 6.9% income lost. Assuming 52 working weeks x 5 working days = 260 working days a year. 18/260= 0.069.
12.5% pay increase over 3 years
-6.9% lost salary
= 5.6% over 3 years. That's about 1.87% each year.
I know this is linear math but you get the idea. No wonder only 55% voted for it.
