This isn't without discussion. There have been months (probably years) of discussion.
No-one will lose their job. No-one will lose salary. No-one will lose breaks.
The change involved is 3 hours more on one shift, and 3 hours less on another.
I just don't understand why some of the more militant unions oppose every single management change, instead of being constructive.
Although I don't support striking for pay, it at least has a fairly understandable logic to it. Where is the logic in this strike?
