Email

It is a centralized repository where announcements, general interest news, company manuals, among others, are published.

This promotes collaboration, besides being a source of knowledge for workers. The information is updated in real time for the entire staff, regardless of their location.

Instant Messaging

Instant messaging promotes collaboration in remote work teams and the agile resolution of doubts or problems.

Workplace climate surveys

Regular workplace climate surveys among employees can provide valuable information about the effectiveness of your internal communication efforts.

These surveys can provide valuable information that goes beyond the effectiveness of the tools used. They also offer insights about the work environment, organizational culture, and the quality of work relationships.
