Rapid Union Growth Provokes a Hostile Reaction
These periods of rapid union growth end because social upheaval provokes a hostile reaction. Union growth leads employers to organize, to discover their own collective interests. Emulating their workers, they join together to discharge union activists, to support each other in strikes, and to demand government action against unions. This rising opposition ends periods of rapid union growth, beginning a new phase of decline followed by longer periods of stagnant membership. The weakest unions formed during the union surge succumb to the post-boom reaction; but if enough unions survive they leave a movement larger and broader than before.
