The Workers' Compensation poster is hung, the schedule of paid holidays is posted and employees get it - they must wash their hands before returning to work. Congratulations, you have successfully executed what passes for internal communications in many organizations.
Of course companies aren't going to see higher returns as a result of those efforts, but that's no reason to underestimate the importance of well executed internal communications. Managed properly, IC can be an effective strategic tool to help boost engagement, performance, retention and yes, even the bottom line. This is especially true for organizations with employees spread out across far-flung regions.
