At first glance this company appears to have it's act together. Aptitude test, prompt interview and extensive safety training. What it doesn't do is prepare you for the atmosphere on the plant floor.
As far as unions go, this is the worst example i've come across. Toxic. Keep in mind this is a box factory; nobody is saving lives or solving world peace. People here treat their employee numbers like a rank to be saluted.
You'll be under the microscope for your 6 month probation, fair enough. But it's not just management you have to justify your existence to. 1/10 plant workers here are tolerable, 1/20 is even pleasant. I feel badly for temp workers from the agency who are treated with casual disdain.
The work itself isn't bad. On a slow day, you'll be sweeping the floor for 8 hours. On a busy day, you're feeding Ace Bakery boxes at speed for 8 hours. The environment itself isn't terrible either. Noisy, hot, dusty but you get used to it.
If you love social politics and feel like ingratiating yourself to some of the most ignorant people in Ontario, this is the place for you. Otherwise, don't bother.
