I think the point was that these workers were having to work 45 hours anyway and were not eligible for overtime pay.
Usually workers stick it to The Man more than The Man sticks it to the workers.
Yes, I know. But at least, as they noted, with the higher base pay they were “guaranteed” that much per week. Now, it will depend on their boss whether they make up the 15%.
Either way, at 45 hours they will be making the same as before. Of course if they work more than 45 hours they’re better off. The question is, will this happen ?
Net: uncertainty, resentment.
