TL;DR
- Teams works for desk-based workers. It structurally excludes the ~80% of staff without a corporate email or M365 licence.
- Only 30-40% of frontline workers actively use Teams; dedicated employee apps reach 80-97% registration.
- In 2025 the gap widened: Copilot needs M365, so the workers already locked out of Teams are now locked out of AI at work too.
Microsoft Teams is built for people with a desk, a corporate email, and a managed M365 device. That describes maybe one in five of your employees.
The other 80% work without a desk. Field, care, retail, logistics, production. Teams was never designed to reach them, and no amount of extra configuration changes that. The barrier is the entry point, not the feature set. That is the whole case for building a mobile-first intranet: mobile-first is a reach decision, not a design one.
The numbers make the gap concrete. Only 30-40% of frontline workers actively use Teams. Dedicated employee apps reach 80-97% registration among the same group. Same workforce, different entry point, roughly double the reach.
The AI access gap that opened in 2025
Until recently, the Teams-versus-employee-app debate was about chat and features. Microsoft 365 Copilot changed the stakes.
Copilot runs on M365 licences. So the frontline workers who cannot onboard to Teams also cannot use Copilot’s AI-assisted summaries, drafting, and recommendations. The tools that are starting to define how work gets done are landing with the people who already had the most support, and skipping the people who had the least.
The question for a comms or HR leader is simple: which half of your workforce are you comfortable leaving outside the AI era?
Teams and an employee app solve different problems
This is not a choice between two products that do the same job. They cover different populations.
| Microsoft Teams | Dedicated employee app | |
|---|---|---|
| Built for | Desk-based knowledge workers | Every employee, desk or not |
| Requires | Corporate email, M365 licence, managed device | A personal smartphone |
| Frontline adoption | 30-40% | 80-97% |
| Copilot / AI access | M365 licence holders only | Available to all users |
| Best at | Meetings, documents, project collaboration | Reaching and engaging the whole workforce |
Teams is very good at what it does for knowledge workers. An employee app closes the reach gap for everyone else. Most organisations with a mixed workforce run both.
What a dedicated employee app does differently
An employee app does not ask for a corporate email or a managed device. It meets people on the phone already in their pocket, which is why adoption looks so different.
AOK uses tchop to reach clinical staff who do not have a desk or a company login. Their employee app case study shows what that reach looks like in practice: a direct line to every employee, not just the ones IT already provisions.
The cost of forcing one platform to do everything
Running all internal communication through Teams looks efficient on paper. In practice it writes off the majority of the workforce.
Poor internal communication is one of the biggest drivers of people leaving. 63% of employees weighing a job change name it as a key reason. The bill for leaving frontline staff unreached shows up in productivity, and then it shows up in turnover.
A dedicated app gives every employee a direct line, whatever their device, licence, or IT setup.
FAQ
Can Microsoft Teams work for frontline employees?
It can for some, but adoption stays low. Teams needs a corporate email, an M365 licence, and a managed device, and most frontline workers have none of the three.
What is the difference between an employee app and an intranet?
An employee app is built for high adoption across the whole workforce, including staff without desks. A traditional intranet is built for desk-based workers on corporate devices.
What does Microsoft 365 Copilot require to work?
An M365 licence, which in turn means a corporate email and a managed device. That puts it out of reach for most frontline workers.
How does employee app adoption compare to Teams for frontline workers?
Dedicated employee apps see 80-97% registration among frontline workers, against 30-40% for Teams.
Does an employee app replace Microsoft Teams?
No. They solve different problems. Teams handles meetings, documents, and collaborative projects for knowledge workers. An employee app solves reach for frontline staff who have no Microsoft identity. A mixed workforce usually needs both.
