Best slack Alternative for team communication to connect everyone in an enterprise - seamlessly, securely, and productively for your business. There are scores of apps out there promising seamless employee communication and collaboration. One of the market stalwarts that has shown high adoption and growth is, inarguably, Slack. But is the platform right for everyone? Not quite. Slack does not serve the 2.7 billion-strong global non-desk workforce. That way, it fails to optimize its communication and collaboration potential. While Slack is a great tool for desk-bound workers, it’s wise to look for a Slack alternative if you’re looking for a communication tool for frontline workers.
