How Labor Unions Can Increase Membership With Technology: 8 Proven Tactics

Summary

Labor union membership has been on the decline for years, even as public support keeps climbing. This article highlights eight proven ways unions can use technology to reverse the trend—ranging from SMS and voice alerts to digital grievance reporting, social media outreach, and virtual events. It explains how electronic authorization cards, member portals, and peer-to-peer texting help unions modernize recruitment and retention. It also shows how DialMyCalls provides a secure, scalable platform for union communication, helping organizers reach members instantly, protect privacy, and grow stronger in today’s digital-first world.

1. Use SMS & Voice Alerts for Recruitment Drives

One of the most challenging obstacles for labor unions today is recruitment; while traditional approaches such as talking to workers through door-to-door conversations or leaflet distributions outside of the workplace are still important, they are no longer sufficient. Workers expect prompt, clear communication, which is exactly what SMS alerts and voice broadcasts provide.

Announce Meetings and Drives Instantly

With SMS alerts, unions can send out reminders about informational meetings, membership drives, or rallies in seconds. For example:

Voice broadcasts extend that reach to workers who may not rely on text messaging or email. This is helpful for older members or employees who prefer voice over text.

Enable Two-Way Communication

Recruitment works best as a conversation and not as a broadcast. With two-way SMS, potential members can reply with questions, requests for additional information, or requests to sign up directly. For example, workers can reply “YES” to a text about information regarding the union and be automatically added to a list for follow-up.

How DialMyCalls Helps

Platforms like DialMyCalls make this process seamless by offering:

• Mass texting and voice broadcasting to reach large groups quickly.
• Consent management tools to ensure communications comply with legal requirements.
• Auto-replies that acknowledge sign-ups or queries instantly.
• Shared numbers so members can reply without confusion, even when multiple organizers are texting.

All in all, the easier it is for workers to join unions, the higher the chances that they will take that first step in joining. By utilizing SMS and voice alerts, organizers can meet workers where they are, on phones, while establishing a quick and easy entry point to the union.

2. Implement Electronic Authorization Cards

Historically, one of the most tedious steps in union organizing has been collecting union authorization cards, the documents that workers sign to express interest in developing a union. Traditionally, organizers had to physically track down employees, often after work hours, to collect their physical signatures. This was slow and, in some situations, allowed for employer interference in the process.

Now, the National Labor Relations Board (NLRB) allows electronic authorization cards that use a secure e-signature. This has changed the organizing landscape. Digital cards provide the same legal backing as paper cards and eliminate some of the logistical barriers of union organizing. Workers can sign on their phones or laptops so that organizers can quickly get to a point of demonstrating a “showing of interest”.

Why This Matters for Modern Organizing

Electronic cards are particularly valuable in two scenarios:

• Remote onboarding: For industries where workers are dispersed or partially remote, digital cards keep the process moving without face-to-face delays.
• Hostile environments: In workplaces resistant to organizing, e-cards reduce the need for on-site solicitation and minimize the risks of employer retaliation or intimidation.

How Technology Strengthens the Process

When paired with communication tools like DialMyCalls, organization leaders are able to send safe links to digital authorization cards through text or email. Tools like consent management and message tracking support compliance and create transparency, but also help to alleviate the friction that often slows union campaigns down.

Therefore, with electronic authorization cards, labor unions can expedite the unionization process and reduce associated risks while making it easier for workers to take action. What once required weeks of legwork can now be accomplished in days, all while complying with current U.S. labor law.

3. Launch Member Portals & Mobile Apps

For unions, member engagement doesn’t stop at recruitment. The harder part is retention—ensuring that members remain connected, informed, and active in union life. Digital tools like member portals and mobile apps are essential to achieve this by ensuring that workers have easy access to what they need, all in one location.

Digitize Resources and Services

Rather than having to depend on phone calls or paper notices, unions can set up a portal for members that will allow them to:

• Report grievances and workplace incidents securely.
• Register for training, events, or town halls.
• Access collective bargaining agreements, FAQs, and educational resources.

Examples in Practice

• The AFL-CIO has supported projects like LaborNet, which serve as digital hubs for union members.
• Many unions now run their own portals and forums, creating spaces for discussion, updates, and resource sharing.

Mobile Access Is Key

Since most workers are carrying a smartphone, mobile apps guarantee that all of the important information is easily accessible, even for members who do not normally have access to computers. A union app can send push notifications to remind members of a meeting, show them dues payment schedule, or even provide a secure chat for members.

DialMyCalls Connection

While portals provide centralized resources, DialMyCalls provides a great supplement by pushing out time-sensitive alerts to members; reminders to log in and vote on a contract, or even sending a text to let members know to remember to complete their online grievance form.

4. Leverage Social Media & Digital Storytelling

Social media is potentially one of the most powerful tools for union organizing. Social media platforms, like X (Twitter), Facebook, TikTok, and Instagram, provide unions the ability to directly reach many workers at scale, relay testimonials, and help develop broader public support.

Amplify Campaigns and Stories

Digital storytelling, such as a video of a worker speaking about how their union improved their wages or safety, humanizes the organizing effort. Campaigns that exemplify solidarity are able to go viral within hours and reach potential members who might never see a flyer or attend a meeting.

Understand the Limitations

There are constraints to algorithms. A super effective video could still be buried deep in a worker’s feed, and corporate platforms can suppress union content. This is why it is important to combine social media channels with direct messaging channels like SMS, voice broadcasts, and email to guarantee critical updates are delivered.

Why It Is Important

Social media can be an important way to share awareness and build momentum, but unions should use a multi-channel approach. While social media storytelling can help you keep the public inspired or supportive, direct communication processes can build commitment and evoke action.

DialMyCalls Role

Social media can generate interest, but SMS and voice alerts via DialMyCalls can ensure those interested workers get timely invitations to meetings, links to e-cards, or reminders about organizing drives. Together, you’ll have a full-spectrum outreach approach.

5. Peer-to-Peer and Text Organizing

Sometimes, the most powerful organizing tool is not a message broadcast to hundreds of people; it’s a personal message. Peer-to-peer (P2P) texting allows union members to reach out to potential new members from their personal devices at scale, but still keep the interaction personal.

Why Peer-to-Peer Works

In contrast to a typical cold outreach where a stranger sends a generic text and/or call to a person they have never met, the peer-to-peer is based on trusted agents—co-workers or fellow union members—that make the message feel more legitimate. Research shows that people are more likely to respond to peer-to-peer texts than they are to organizations they have never interacted with. For unions, that translates into better engagement and higher conversion rates when mobilizing new members.

Scaling Personal Outreach

Organizers can use targeted tools to train dozens or even hundreds of members to text recruits at the same time. Each text can be customized while still being able to reach hundreds of workers in a single night. This combination of scale and authenticity makes P2P SMS one of the most powerful types of digital organizing tactics.

Integration with SMS Platforms

Peer-to-peer campaigns can also integrate with text platform services through API’s. Platforms like DialMyCalls allow for these workflows to be cleanly executed and allow unions to utilize contact lists, track opt-ins, and be able to document responses in a compliant manner. This way, even decentralized campaigns will meet consent requirements and still align with the strategic goals of the union.

Overall, building trust is core to organizing, and P2P texting serves as a simple way to emulate the personal conversation that has always driven union growth—now, it is just quicker, using digital technology. By coupling personal outreach with the scalability offered by modern SMS platforms, unions can reach people in more places while still maintaining authenticity.

6. Data-Driven Digital Campaigns & Targeted Outreach

Union organizing has always relied upon understanding the needs of members. And while that has not changed, union recruitment technology now makes it much more accurate. Data-driven campaigns allow unions to segment audiences, test strategies, and measure outcomes – making outreach smarter instead of just louder.

Segment Audiences for Relevance

Concerns about workplace conditions are not the same for every worker. For some new employees, understanding their rights in the workplace may be their main concern, while more seasoned employees may be thinking about contract negotiations or retirement benefits. Unions can segment audiences based on demographic characteristics, job type, or industry, allowing them to develop messages that resonate differently with each group.

Use A/B Testing to Refine Messaging

Digital tools have made A/B testing easier than ever before—sending two versions of a message to determine which performs better. For instance, one recruitment text could point out higher wages, and the other may emphasize job security. By tracking which message earns the most sign-ups, unions will be able to improve their messaging.

Track Engagement Metrics

Numbers matter. With digital outreach, unions can track:

• Inquiries: How many workers requested more information.
• RSVPs: How many signed up for an informational meeting or town hall.
• Response rates: How often members engage with messages or surveys.

This data provides real-time insight into what’s working and where adjustments are needed.

How DialMyCalls Can Help

With DialMyCalls, unions can organize contact lists, plan targeted SMS or voice broadcasts to reach specific members, and analyze delivery and response reports. This means campaigns are not only broad but also precise and measurable.

The bottom line is that by relying on data instead of guesswork, unions can use their resources more effectively, develop sharper campaigns, and show members and leadership clear results. It makes outreach a cycle of continual learning and improvement.

7. Digital Grievance Reporting & Incident Disclosure

One of the most impactful functions of unions is to offer workers a practical way to file a grievance. It is vital to document and address issues, whether they are harassment, unsafe working conditions, wage theft, or another grievance. Technology has the potential to make the entire process faster, safer, and more transparent.

Online Grievance Forms and Reporting Tools

Unions can develop an online grievance platform that allows members to file complaints confidentially from a phone or computer, rather than filling out a paper grievance form or taking the informal, word-of-mouth approach. This online union tool removes barriers to reporting and creates a digital record of what members are complaining about, and an important resource during negotiations or litigation.

Petitions and Collective Action

Digital tools also facilitate solidarity in other ways. Online petitions enable members to collectively sign on to issues that they care about—such as demanding fair work schedules or challenging unsafe workplace policies. The messages sent through these collective signals mobilize change and amplify shared member support.

Blogging and Public Disclosure

At times, creating awareness is just as valuable as filing complaints. Unions can help to expose workplace wrongdoing and push for change via blogs and other forms of digital storytelling. First-hand accounts of bad conditions or unfair treatment can motivate some workers to move closer to joining, and draw public attention to corporate practices.

The Role DialMyCalls Plays

Platforms like DialMyCalls could be combined with grievance procedures to educate membership about new petitions, provide updates on the outcomes of grievances, and inform members when they should take action. Mass texts and voice calls are a useful way to ensure that key updates don’t get lost in overcrowded inboxes.

All in all, a union’s strength comes from amplifying worker voices. Digital grievance reporting and disclosure tools protect members, increase transparency, and make organizing campaigns harder to ignore. By combining secure reporting with broad communication, unions can transform individual concerns into collective action.

8. Virtual Events & Community Building

A strong union is not just about signing cards or managing grievances – it is also about belonging. In-person meetings are still really important, but we now have the ability to take that sense of community online through virtual events and digital engagement spaces.

Webinars and Training Sessions

Unions can run webinars to teach members about their rights at work, health and safety procedures and protocols, updates or changes to collective agreements, or other related matters or topics. Webinars can be recorded and shared, which gives members the option to engage on their own time in a more convenient manner.

Virtual Town Halls

Platforms such as Zoom or Teams allow unions to hold town halls that are open access or committee-based, where leaders and members can discuss issues in real time. If workers are in dispersed industries or if in-person meetings are difficult, the virtual town hall ensures every voice has a chance to be heard.

Peer-to-Peer Connections

While formal events create a useful environment, digital spaces allow for peer introductions and informal networking. A new member may join a breakout session or forum discussion and immediately feel part of something bigger, which helps reinforce their loyalty and long-term membership.

Where DialMyCalls Stands

With DialMyCalls, organizers can send mass reminders for these virtual events – “Union Town Hall: Wednesday, 7 PM. Click here to join live” – to ensure members won’t miss an opportunity to connect and participate, wherever they may be.

The bottom line is that solidarity thrives on connection. Providing digital places for members to learn, share, and support each other contributes to both the union’s numbers and its culture. Virtual events allow unions to extend the reach of the union hall into every worker’s living room—supporting retention and reinforcing the sense that every member matters.
