It would be a great job if for the first 2-3 years you got more than 2-3 days off a month and were able to know what the days off were before 7:30am the day off when they call you to tell you that you are off.
No benefits, no retirement, bad health care, terrible hours, pay not worth the work, seniority based, takes years to move up, then right when you think you have a career position someone transfers and takes it. Older employees get paid twice as much as you do half the work and get tons of sick and vacation pay. They will never retire because they have it to easy and have the new, younger employees to do all their work. Terrible le system, union is terrible as well.
