UNION ORGANIZING

Reach every worker before the vote. Across every shift, site, and channel.

Organizing drives fail when workers go unreached. CallHub coordinates calls, texts, and relational outreach so no worker slips through before authorization or ratification day.

  • Call, text, and relational outreach coordinated from one campaign, not three disconnected tools
  • Automated follow-up sequences across channels so unreached workers get a second and third touch
  • One live contact record per worker, updated in real time across every volunteer interaction
  • Built-in TCPA compliance, CRM sync, and shift-hour scheduling. Included on every plan.

THE PROBLEM

Scattered outreach loses authorization drives before the vote is called.

Your phone team works one list. Your texters work another. Nobody knows which workers are still unreached. Management is already running counter-messaging.

Most workers need 4–6 contacts before signing a card

A single cold call doesn't move an undecided worker. Especially not when management has daily access to them on the floor. You need repeated, trusted touches across channels.

Shift workers and gig workers are nearly impossible to reach

Workers on split shifts, overnight rotations, and contractor arrangements don't answer at the same hour. One-size outreach hits voicemail and stops. The contact is lost.

Lists fragment across tools. No one knows who's been reached.

Callers export one list. Texters maintain another. Relational organizers track a third. Workers get double-contacted or missed entirely. There's no shared record.

HOW IT WORKS

Every capability your organizing drive needs, from first contact to ratification

Organizing isn’t a single channel or a single moment. CallHub gives your team the tools to identify supporters, persuade the undecided, mobilize members, and coordinate action. All from one platform.

Worker ID Calls

Find your supporters before management finds your organizers.

The first job in any drive is knowing who’s with you, who’s persuadable, and who’s against. CallHub lets volunteers run structured worker ID phone banks with custom survey scripts. Every response auto-tags the contact in real time. No spreadsheet cleanup. No lost data between shifts.

  • Call Center Software: run structured worker ID calls with branching survey logic and real-time disposition tagging
  • Predictive Dialer: keeps volunteers on conversations, not waiting for calls to connect, maximizing talk time per shift
  • Segments & Auto-Tagging: supporters, undecideds, and hard nos are auto-segmented as responses come in, with no manual work
  • Language Routing: non-English-speaking workers connect automatically to bilingual volunteers for higher conversion

Authorization card drive outreach

Authorization Card & Petition Drives

Move undecided workers across channels before management does.

Undecided workers don’t sign from a single phone call. They need consistent contact over days, across multiple directions. CallHub combines P2P texting with phone banking so volunteers reach persuadable workers in high-volume, personal conversations. When a text exchange gets warm, escalate to a live call in one click.

  • P2P Texting: high-volume, one-to-one text conversations with undecided workers; volunteers handle real replies personally
  • In-Chat Calling: escalate a warm text exchange to a live call instantly, at the moment of highest interest
  • Workflow Automation: set call → text → email follow-up rules once; sequences run automatically for every unreached contact
  • Inbound Call Handling: workers who missed your call can call back directly into the campaign, with a 3.5% callback rate

Relational Organizing

Reach workers your organizers can’t. Use the contacts they already trust.

A call from an organizer is easier to dismiss than one from a coworker. Relational organizing lets your existing supporters reach their own networks with guided scripts. Every outcome (signed, undecided, declined) syncs back into the central campaign record automatically.

  • Relational Organizing: members contact their own networks with guided scripts; all responses feed back into the campaign record
  • Workflow Automation: define follow-up triggers once; automated sequences continue outreach on relational contacts without daily management
  • Segments: contacts surfaced through relational outreach are auto-segmented and routed to the right next action

Member mobilization and action alerts

Member Mobilization & Action Alerts

Turn signed cards into showing up. At the vote, the rally, or the table.

Signing a card is one thing. Showing up on vote day, or at a contract action, is another. CallHub coordinates text broadcasts, voice reminders, and automated follow-up sequences to move confirmed members from passive support to active participation. Set the sequence once and let it run.

  • Text Broadcasts: send personalized action alerts to your full confirmed member list in one send, with timezone-optimized delivery
  • Voice Broadcasting: reach members who prefer calls with a pre-recorded message at scale, without tying up volunteers
  • Recurring Campaign: schedule the full reminder sequence in advance and let it run without day-of management
  • Timezone-Optimized Outreach: every message sends during the worker's local permitted hours, regardless of where your team is based

Contract Campaigns & Bargaining Support

Keep members informed and engaged through every round at the table.

Bargaining campaigns require sustained communication: updates after each session, action alerts when pressure is needed, and fast mobilization if a deadline hits. CallHub gives your team one place to run all of it. One contact record per member across every channel, no reconciliation needed.

  • P2P Texting: send bargaining updates and action calls personally, with volunteers handling member replies in real time
  • Agent Quality & Coaching (AI): AI feedback flags underperforming volunteers daily, with a 25% performance boost across the phone bank
  • Built-in TCPA Compliance: automatic litigator scrubbing, landline detection, and 8am to 9pm local hour enforcement on every outreach
  • Live Monitoring Dashboard: supervisors see every active call, volunteer stats, and contact rates in real time from one view

WHAT UNIONS SAY

Hear from unions winning with coordinated outreach

"

Our goal was to get members involved in our pay campaign. Signing the Government petition was the mechanism. Our target was 100,000 signatures. That number secures a Parliamentary debate. We achieved it after using P2P texting.

"We needed 40,000 more signatures in under a week. Phone and email weren't enough. P2P texting through CallHub got us 10,000 signatures in a single day. The response rate is in another league entirely."

"Hospo Voice used P2P texting and email through CallHub to reach workers across Australia. Workers scattered across casual roles are hard to reach through traditional channels. Digital tools plus on-the-ground action made the campaign work."

FAQ

Common questions about running organizing drives on CallHub

Can we keep our outreach confidential from the employer during an organizing drive?
Yes. CallHub campaigns are run from your account and employer access is never granted. Caller ID, script content, and contact lists are entirely within your control. Volunteers call and text from CallHub numbers, not personal devices, keeping organizer identities protected.
How do we reach workers across different shifts and time zones without violating contact hour rules?
CallHub's timezone-optimized delivery automatically schedules every message within permitted hours based on the worker's local time. You configure the campaign once and CallHub handles timing across every region, shift pattern, and time zone without manual intervention.
We're running worker ID calls and authorization card outreach at the same time. Can CallHub handle both from one campaign?
Yes. Workflow Automation lets you define separate sequences for separate contact segments: ID calls for new contacts, follow-up texts for undecideds, escalation calls for warm leads. Every channel reads from the same contact record, so there's no double-contacting and no lost data between activities.
How does CallHub handle non-English-speaking workers in multilingual worksites?
CallHub's language routing automatically connects non-English-speaking workers to bilingual volunteers when available. You configure language preferences at the campaign level. Contacts are matched to the right agent without manual assignment, resulting in an 8% improvement in outcomes from non-English contacts.
How far in advance can we schedule mobilization outreach for a ratification vote or contract action?
You can schedule campaigns days or weeks in advance. Build the full ratification or action alert sequence ahead of time and let it run. Timezone-optimized delivery ensures no worker is contacted outside permitted hours, regardless of when the campaign was set up.
Is CallHub suitable for a single-worksite organizing committee, not just large international unions?
Yes. CallHub scales from a 200-worker single-site drive to national multi-worksite campaigns. There's a free tier for campaigns under 10K contacts. Many organizing committees use CallHub for a single bargaining unit without needing enterprise setup.
