Transitioning hard-core Slack users to Teams

KarenD69 A couple of suggestion for motivating them to make the transition.

1. Take their complaint and show them how to fix it. You should be able to create a bot that will take a comment and convert it into a recurring reminder/task. It's more work up front than a built in "/remind" but it highlights how extensible Teams is compared to Slack.
2. Focus on their annoyances with Slack and show how Teams makes those things easy. When they understand the strengths of the Teams platform--integration being one of the biggest--when compared to what they are doing in Slack, then you can help them see that using Slack is still chockablock full of tradeoffs in functionality. The question then becomes which tradeoffs are the hardest to deal with.
3. Ask other teams in your company about their experiences and what they have found to be much easier in Teams than Slack. you can then present the experiences of that team's peers to show them the best way forward. Nothing is as convincing as personal recommendations, especially if they come from someone who resisted the change originally and then became a fan of the new system.

The idea is to show the transition as beneficial as possible while acknowledging the perceived functional losses. When they understand the greater potential of Teams vs. Slack for the work they are doing, they should get on board more easily, or at least not be so obstinate about the transition. This is the carrot approach of the job you have to do.

There will always be those who refuse to change willingly. For them, you will have to set a hard deadline. You can also let them know that their resistance to the change and it's subsequent impact on the company's ability to perform effectively and efficiently will be noted in their annual reviews. The is the stick approach of the job.

After all, your ability to get them to transition gracefully to Teams will be noted on your annual review, too.
