Many US jobs are based off an hourly rate, some with overtime (usually not added in). I noticed other posters mentioned Xmas bonus. As an hourly worker I received a standard 3% yearly raise to cover increased costs of living. Because our cost of living increase was nearly double that, our salary actually declined. Oh and that Xmas bonus... If you count a 25$ gift card to Walmart a bonus...
Pretty shit, but it could be worse.
