Free Workers - Free Industry United-we'll Win!" poster
The pattern
This still is filed under Us-versus-them positioning.
Define
The buyer is invited into a side. The product is what we use. The named other is what we refuse.
Mechanism
Identity contrast. Choosing the offer is choosing a group. The out-group does as much work as the claim.
Verdict
The category is crowded
Why it works
Emphasizes unity between labor and management/industry against a common foe. It flatters both the individual worker and the overarching industrial system.
Steal this when
You need to unify two historically opposing groups by focusing on their shared identity and shared goal.
