Is Instant Messaging Actually Improving Workplace Collaboration?

*Updated 21 September 2026*

Instant messaging has become a normal part of working life.

The question for organisations is no longer whether employees should be able to message one another.

It is whether those messages actually help work move forwards.

Teams can now communicate through Microsoft Teams, Mitel, 8x8, Zoom and numerous other applications. Add email, meetings, telephone calls, project-management systems and AI tools, and employees can quickly find themselves working across more channels rather than communicating more effectively.

Microsoft's 2025 Work Trend Index found that 48% of employees said their work felt chaotic and fragmented. It also found that employees were receiving an average of 58 messages outside the traditional working day, highlighting the risk of allowing real-time communication to become constant communication.

At the same time, flexible working remains established in the UK. The Office for National Statistics reported in June 2025 that 28% of working adults in Great Britain had hybrid worked between January and March 2025.

Instant messaging therefore still has an important role.

The challenge is designing it as part of enterprise communications, rather than creating another stream of notifications employees need to manage.

What Is Workplace Instant Messaging?

Workplace instant messaging allows employees to communicate through real-time or asynchronous text conversations.

Modern platforms often extend considerably beyond basic chat and can include:

• One-to-one messaging
• Group conversations
• Persistent team channels
• Presence and availability
• File sharing
• Voice calls
• Video meetings
• Screen sharing
• Mobile collaboration
• Workflow integrations
• AI assistance
• Searchable conversation history

This is why instant messaging is increasingly part of unified communications rather than a standalone application.

Britannic's Unified Communications approach connects voice, video, messaging and collaboration across cloud, on-premise and hybrid environments, helping organisations design communications around how employees actually work.

Why Is Instant Messaging Useful In The Workplace?

The strongest use case for messaging is speed without formality.

Not every interaction needs an email, meeting or telephone call.

A short message can be effective for:

• Quick questions
• Status updates
• Sharing information
• Coordinating teams
• Checking availability
• Resolving straightforward issues
• Asking for assistance
• Sharing documents
• Keeping project discussions together

Messaging can be particularly useful for distributed organisations because employees can communicate regardless of whether they are working from an office, home or another location.

The benefit does not come from sending more messages.

It comes from choosing a lighter communication method when a meeting or lengthy email would create unnecessary effort.

When Does Instant Messaging Become A Productivity Problem?

Messaging can create the opposite outcome when employees feel they need to respond immediately to everything.

Constant notifications interrupt focused work.

Important decisions can disappear inside chat threads.

Employees can become members of too many channels.

The same conversation may be repeated across chat, email and meetings.

Knowledge can become scattered across different platforms.

Microsoft's research showing that almost half of employees describe their work as chaotic and fragmented illustrates why organisations need to think beyond simply giving employees additional communication tools.

A successful messaging strategy therefore needs to answer a simple question.

Which type of communication belongs in which channel?

For example:

• A quick status check may belong in chat
• A complex discussion may need a call or meeting
• A formal decision may need documenting elsewhere
• An urgent issue may require voice
• A project update may belong in a shared workspace
• Information that employees will need later should not disappear inside an informal conversation

The right communication channel depends on the purpose of the interaction.

Why Should Messaging Be Part Of Unified Communications?

Standalone messaging creates another destination employees need to monitor.

Unified communications brings messaging together with other communication methods.

Standalone Messaging	Connected Unified Communications
Chat operates separately	Messaging connects with voice and video
Employees switch applications	Communication happens within a common environment
Limited presence information	Employees can see availability before contacting colleagues
Conversations remain isolated	Calls or meetings can begin directly from a conversation
Separate administration	Policies and users can be managed more consistently
Another application to adopt	Communications can consolidate around fewer platforms

This is where messaging becomes more useful.

An employee might begin with a message, realise the issue is too complex to resolve through text and move directly into a voice or video conversation without starting the interaction again.

That ability to move naturally between communication modes is more valuable than instant messaging alone.

How Does Microsoft Teams Fit Into Enterprise Communications?

Microsoft Teams is already central to collaboration for many organisations.

It provides chat, channels, meetings, file collaboration and integration with Microsoft 365 applications.

However, organisations do not necessarily need to replace their entire communications environment to make Teams more central to how employees communicate.

Britannic's NetX Direct Routing can connect Microsoft Teams with external calling and existing UC and contact centre environments through the NetX SIP platform. This allows organisations to extend Teams into enterprise voice while retaining greater flexibility over routing, numbers and wider communications infrastructure.

That can be particularly useful in hybrid estates where some teams use Teams while other parts of the organisation continue to depend on existing Mitel, contact centre or specialist voice technology.

The goal should not automatically be to standardise every employee onto one product.

It should be to make the wider environment work together coherently.

What Other Unified Communications Platforms Support Messaging?

Microsoft Teams is only one option.

Different organisations have different estates, requirements and existing investments.

Mitel MiCollab

Mitel MiCollab combines messaging, calling, presence, video, voicemail and collaboration across desktop, web and mobile.

Britannic integrates MiCollab with wider Mitel environments, Microsoft Teams, CRM platforms and workflows rather than allowing it to operate as another standalone tool.

8x8 Work

8x8 Work combines voice, video and messaging in a cloud-based UCaaS platform, allowing employees to communicate through one application across devices.

Zoom Workplace

Zoom now extends considerably beyond meetings.

Its collaboration environment includes Team Chat alongside calling, meetings, documents and other productivity capabilities, allowing messaging to form part of a wider workplace environment.

The technology decision should therefore begin with how employees need to communicate and what needs to integrate, rather than selecting a platform because its chat interface is familiar.

How Should Businesses Manage Messaging Overload?

Good messaging governance should reduce interruptions rather than introduce unnecessary restrictions.

Employees should understand when they are expected to respond and when a message can wait.

Useful principles include:

• Use channels and groups for defined purposes
• Avoid adding employees to conversations they do not need
• Use presence information before interrupting colleagues
• Respect working hours and time zones
• Use notification settings appropriately
• Avoid treating every message as urgent
• Move complicated conversations into voice or video when appropriate
• Record important decisions in the appropriate business system
• Use approved platforms for business information
• Apply organisational data-handling and retention policies
• Regularly remove redundant channels, groups and tools

The current article's recommendation that sensitive company information should simply not be discussed through instant messaging is too broad.

Enterprise messaging platforms can support secure communication, but organisations need clear policies covering which platform is approved, what information may be shared, retention requirements and who can access it.

How Can Presence Improve Workplace Communication?

Presence is one of the quieter advantages of unified communications.

Knowing whether somebody is available, busy, presenting, in a meeting or offline helps employees decide how and when to contact them.

Instead of immediately sending another message, an employee may decide to:

• Wait
• Send an asynchronous update
• Call another available colleague
• Schedule a meeting
• Route the question elsewhere

Platforms such as MiCollab provide real-time presence information alongside messaging and calling.

Used correctly, presence can help move workplace communication away from the assumption that every employee should always be immediately available.

How Is AI Changing Workplace Messaging?

AI is beginning to change what employees do with conversations after they happen.

Modern collaboration platforms increasingly use AI to:

• Summarise conversations
• Identify actions
• Find information
• Condense long message threads
• Prepare meeting summaries
• Generate responses
• Surface relevant documents
• Help employees catch up after being away

For example, Zoom Phone includes AI capabilities such as condensed SMS thread summaries and extracting tasks from communications.

Microsoft's 2026 Work Trend Index, based on a survey of 20,000 AI users across ten countries alongside Microsoft 365 productivity data, found that 58% of AI users said they were producing work they could not have produced a year earlier. Microsoft also concluded that organisational factors had substantially more influence on reported AI value than individual effort alone.

That reinforces an important point.

Adding AI to messaging does not solve poor communication design.

Organisations still need to decide how work should flow, which information matters and where decisions should live.

The Britannic Connected Communication Framework

A stronger approach to workplace messaging can be built around five principles.

1. Purpose - Define what messaging should be used for and where another communication method is more appropriate.
2. Presence - Use availability information to help employees choose when and how to communicate.
3. Connect - Integrate messaging with voice, video, collaboration tools and relevant business applications.
4. Control - Apply appropriate security, retention, access, notification and communication policies.
5. Improve - Review adoption, user feedback and communication patterns to identify unnecessary tools or friction.

Purpose → Presence → Connect → Control → Improve

The aim is not to maximise messaging.

It is to make communication easier to navigate.

What Should Businesses Review?

Organisations reviewing instant messaging and workplace collaboration should ask:

• How many messaging applications are employees currently using?
• Are employees duplicating conversations across chat and email?
• Which platform should employees use for which purpose?
• Can messaging move naturally into voice or video?
• Can employees see colleague availability?
• Are Teams, telephony and other communications connected?
• Are important decisions being recorded in the right place?
• Are employees receiving unnecessary notifications?
• Are working hours and time zones respected?
• Are messaging platforms approved and appropriately secured?
• Are retention and compliance requirements understood?
• Can employees collaborate consistently across office, home and mobile environments?
• Are communications integrated with relevant business applications?
• Are unused licences or overlapping tools creating unnecessary cost?
• Are AI features supporting useful work rather than increasing noise?
• Is adoption being reviewed after implementation?

The final question is important.

Deploying a collaboration platform does not guarantee better collaboration.

How the organisation designs, governs and continuously improves its communication environment determines whether employees actually benefit from it.

Instant Messaging Should Reduce Communication Friction

Instant messaging is no longer an emerging workplace technology.

It is infrastructure for everyday collaboration.

That makes the conversation around it more mature.

The objective is not simply faster replies.

It is giving employees the right communication method at the right moment while avoiding unnecessary meetings, duplicated applications and constant interruptions.

Britannic helps organisations design and integrate unified communications environments across Microsoft Teams, Mitel, 8x8, Zoom, NetX and existing enterprise voice infrastructure, with ongoing optimisation through its managed services and Customer Success approach.

The result should be a communications environment where messaging, voice, video and collaboration support work rather than compete for employees' attention.

Organisations reviewing workplace communications can book a complimentary meeting with Britannic to assess collaboration tools, identify unnecessary overlap and determine how messaging, voice and video can work together more effectively.
