Pros: benefit package, so so pay, not much is expceted of you
Cons: shift rotation, boring work, infighting, lay offs, impossible to move ahead
The union stands up for employees and the office hates that so it becomes very two faced very quickly. Everyone is always worried about the next layoff, you will be worked like dogs doing tons of overtime then the next week laid off with no warning. this happens every 4 years, it is a predictable cycle of over working people then sacking them. A decent company would be able to figure out scheduling to avoid these cycles but instead they simply keep hiring and laying off.
They don't care about you no matter what they tell you don't fall for it!
