This was a tactical move, i suspect. Restless employees at Wal-Mart type stores can generally get on with another nickel on their paycheck and an angry-dome presentation on how unions will destroy the world. Not so here.
When your employees are filing for food stamps and urinating in plastic bottles, things are only a few war-boys away from Mad Max. No amount of safety meeting shilling is going to convince these people...many of whom source Amazon as the only major employer in the region...that a union is bad. Amazon likely raised wages to prevent the larger thread: mass unionization across its warehouses that could spread to managers, programmers, SRE teams, etc..
