Honestly, not surprised. Starbucks's strategy on unions seems to be to union-bust as viciously as possible with the thinnest of pretenses, and trust that the federal government will let them do it with a slap on the wrist (if anything), as it always has.
> It’s against the law to fire workers for organizing. But as Rizzo and the other Starbucks workers were learning, there’s also little to stop companies from doing it. The National Labor Relations Board, the federal agency that oversees union elections and protects workers’ rights, has struggled to hold on to staff members amid deep budget cuts. Since 2010, it is down about 520 employees, or 30 percent of its workforce. The primary penalty that it can impose on companies for dismissing pro-union employees — reinstatement with back pay — has been a paltry deterrent, labor advocates said.
This punishment is so tiny it fails to qualify as a penalty at all.
