Employee location has become a bit more complicated as some return to the office, while others work remotely. To embrace those hybrid working conditions, Google is making more changes to its Google Workspace offering by going live with spaces — its tool for small group sharing — in Google Chat for all users.

Spaces integrates with Workspace tools, like the calendar, Drive and documents, to provide a more hybrid work experience where users can see the full history, content and context of conversations regardless of their location.
