They could easily give you a set schedule and leave it that way..the local managers do not want to do that ..not just because of business needs..managers have a brain issue that makes them want to never do anything that helps hourlies on a personal level,,the managers absolutely can not stand the protected time off for that very reason..so if they can mess up block scheduling in a way that is harmful to associates you can bet your last dollar they will....
As petty as it all sounds, I’m sad to say that @YM3BgsL-stl stated the truth in this post.
