Some of you guys hate unions too much you can't see anything but your dislike. Of course you ignore that unions in the 30's and 40's basically created the middle class, but no, you like to hate more.
As pointed out, at $30 an hour a 2000 hour work year adds up to $60k. One of the reasons for the strike is that under current work rules Kelloggs can require that the employees work overtime and on the weekends. Reports have employees going 6 months without a day off. There are stories about employees being required to work up to 70 hours a week. (It seems that after the expense of healthcare and retirement plans, it is cheaper to pay overtime than it is to hire additional employees.) That's how they can get to $120k a year, the additional 30 hours at $45 an hour adds up to $1350 a week easily going over $120k a year.
But do you want to work 7 days a week, 10 hours a day? Cut it to 20 overtime hours a week, that is still over 8 hours a day, 7 days a week.
Kelloggs is also trying to shift more heath insurance cost onto the employees, so what looks like a nice pay increase is instead a reduction in actual income. All while the compensation of the CEO has gone up multiple times to what is now $12 million a year..
