In the many years I have worked for Walmart / Sam's 95 percent of the things they said were for our benefit only hurt us. When they start out describing a new policy or procedure by saying how good it is for us then you can bet very assuredly that it is not. Please allow me to refine my position here. It is not that the policies or procedures in and of themselves are necessarily bad for us but rather that local management never allows them to be as good as they could be. ALWAYS management comes out of the gate twisting and subverting new procedures and policies for the distinct purpose of not allowing them to be good for the workers , well , except foe the favorites. Almost twenty years ago it was announced the schedule was to favor long term associates and that intention has never since then changed on the company's part. But. Local management has at every turn subverted that and lavished better schedules on the favorite people.
The company has a strict no retaliation policy and in cases where it can be proven they deal harshly with managers who do retaliate. But. Managers have perfected retaliation methods that are rarely provable. They use scheduling and work loads and strict policy enforcement as tools of retaliation. Usually the one being retaliated against gets it. They understand that there is retaliation in play. But. Proving retaliation is near impossible in these cases.
Block scheduling will be no different. The favorites will get to choose days off and times to work , the rest of us will suffer.
