What is Slack?

Slack is a messaging app for business that connects people to the information that they need. By bringing people together to work as one unified team, Slack transforms the way that organisations communicate.


Working in Slack

Slack helps you to work in a more connected, flexible and inclusive way.


Slack makes access to your colleagues easy – message anyone inside or outside your organisation and collaborate just like you would in person. People can work in dedicated spaces called channels, which bring the right people and information together.


Slack supports asynchronous work. When work is organised in channels, you can access the information you need in your own time, regardless of your location, time zone or function. Ask questions, catch up with new developments and share updates without having to coordinate schedules. 


In Slack, everyone in an organisation has access to the same shared and searchable information. When teams work together in channels, information can be shared with everyone at once, helping teams to stay aligned and make decisions more quickly.
