Slack is one of the most obvious choices opted for modern workplace communication for a generation of people who can’t stay disconnected from the world for a longer period.

As we’re speaking, there are over 8 million daily active users of Slack, 3 million teams being paid customers. This makes Slack one of the most popular online collaboration tools.

With such a huge turnout of users, it’s not a surprise that there are similar tools jumping on the bandwagon and are identifying themselves as best Slack alternatives.

  1. I would add, and continue to say you have a great article, and that to stay competitive, employees need to be engaged and committed – willing and able to perform at a maximum level and give more. But high performance can’t be mandated or delegated. To be successful, organizations must tap the strengths and passions of each individual employee. Full employee engagement occurs when an employee’s personal values and unique definition of success at work intersects positively with the organization’s financial performance. Executives need to authenticate and lead; managers need to coach, align and recognize daily discretionary effort; and individual contributors need to understand where their passions lie and what they’re skill sets are, then perform and take control of his or her own destination. With a properly assessed internal brand and implemented employee communications program, effective employee engagement can and will improve over time as will company performance. Carla Ernst
