What is a Informal communication?

Updated 30 Jan 2026 5 min read

Informal communication refers to the unofficial, spontaneous exchanges that occur outside formal organisational channels. It includes casual conversations, water cooler chats, social interactions, and the grapevine. While not structured, it plays a vital role in workplace relationships, culture, and information flow.

Understanding informal communication

Informal communication is the casual, unplanned exchanges that happen naturally in workplaces - conversations at the coffee machine, chats between meetings, quick questions to nearby colleagues. While not part of official channels, these interactions significantly shape culture and relationships.

Examples

  • Water cooler conversations
  • Lunch together
  • Chat before meetings start
  • Quick desk-side questions

Characteristics

  • Spontaneous and unplanned
  • Relationship-focused
  • Bidirectional
  • Fast but less reliable

Benefits of informal communication

  • Relationship building: Personal connections strengthen working relationships and collaboration
  • Knowledge sharing: Tacit knowledge often transfers through casual conversation
  • Problem solving: Quick questions get quick answers without formal processes
  • Early warning: Concerns and issues often surface informally first
  • Culture building: Informal interactions shape how people feel about work
  • Trust development: Personal connection supports professional trust

Challenges

The grapevine fills gaps

When formal communication is lacking, the grapevine fills the gap - often with speculation and rumour. The solution isn't eliminating informal communication but ensuring formal channels provide accurate, timely information. People will talk; make sure they have the right information.

  • Misinformation: Rumours and inaccurate information can spread quickly
  • Exclusion: Some employees may be left out of informal networks
  • Inconsistency: Different people hear different things
  • Distraction: Excessive socialising can reduce productivity
  • Unhealthy patterns: Gossip, cliques, and negative talk can develop

Best practices

Enable healthy informal communication

  • Physical spaces that encourage interaction
  • Time for casual conversation
  • Social activities and events
  • Leaders who model approachability

Manage the downsides

  • Strong formal communication to reduce rumours
  • Address gossip and negative patterns
  • Include remote and quieter employees
  • Balance socialising with productivity

Informal communication for remote teams

Creating virtual informal connection

Virtual coffee chats: Scheduled but casual one-on-ones for connection
Social channels: Non-work chat spaces for casual interaction
Meeting buffer time: A few minutes for chat before/after agendas
Virtual social events: Online team activities and celebrations
In-person opportunities: When possible, face-to-face team time

Key takeaways

Informal communication - casual workplace conversations - builds relationships, shares knowledge, and supports culture. It can't replace formal communication but complements it. Enable healthy informal interaction while managing downsides like gossip and exclusion. Remote teams need intentional substitutes for spontaneous office interactions.
