Managements attitude is that you work when they tell you to regardless of your personal plans.
Though it seems to be a well established company worldwide, ADM Port Colborne is a very stressful and demanding place to work. Management does not care about your life outside of work as they feel they can force you into work any weekend they want, even after working 40 hours Monday to Friday. If you do not work the overtime when they tell you to, they can suspend you for not showing up. .
