Who We Serve · Labor Unions

Win contracts. Build power.
Message with certainty.

Grow Progress helps labor unions test the messages that move members, activate fence-sitters, and win public support, with the same RCT methodology used by the country's largest campaigns.

The Challenge

Member mobilization campaigns need to persuade, not just inform.

Misdiagnosis
Knowing where support stands isn't the same as knowing how to move it.
Traditional polling tells you what members already believe. It doesn't tell you which message will move fence-sitters or win public sympathy when it counts.
No evidence
Gut instinct drives message choice.
Contract campaigns, organizing drives, and public fights are decided by message discipline, but most unions pick frames by committee.
Too late
You find out if it worked after the vote.
By the time you know your message wasn't landing, the authorization window has closed. There's no second shot.

Audience Targeting

Reach the right members
with the right message.

Not every member responds to the same frame. Grow Progress helps you identify which messages move stewards, new members, fence-sitters, and public-facing audiences, and tailor your outreach accordingly.

New Members

Build early commitment with frames that connect union values to personal benefit, so new members become active supporters, not passive cardholders.

Fence-Sitters

Identify the exact message that converts skeptical members into active supporters. Stop guessing which frame moves hesitant workers and start knowing.

Shop Stewards

Equip your organizers with tested talking points that hold up in 1-on-1 conversations on the shop floor, not just in rally speeches.

Public Audiences

Win community support with frames that resonate beyond the membership, and shift public opinion before the legislature acts or the press narrative sets.
