Around 80 Google Help subcontractors who recently voted to unionize with the Alphabet Workers Union-Communications Workers of America (AWU-CWA) found out last week that they will be laid off.
To afford good lawyers in order to fight back, unions need money, which requires more members to pay union dues.
To keep politicians honest and to credibly threaten their electibility, unions need more members that can be politically mobilized.
It's a feedback loop. The more people unionize, the more powerful unions become and the more powerful unions become, the more they can protect people who unionize.
