Slack can be a double-edged sword. While it’s a preferred communication tool for many, the average user spends about two hours daily scrolling through messages and channels, often leading to inefficiency and frustration. The author suggests that many Engineering Managers overlook the importance of optimizing their asynchronous communication practices on Slack, which can save significant time and mental effort. The article presents seven practical hacks for better Slack usage. First, filtering to show only unread conversations can cut down on distractions. Grouping channels by priority—like immediate, daily, and weekly reads—helps streamline workflow. The muting feature allows users to manage notification cadences effectively, enabling them to focus when necessary. The author highlights the utility of setting message reminders and using the /remind command to capture thoughts without cluttering the interface. Lastly, entering 'edit mode' to organize sections can be done swiftly, making for a more efficient workspace. These strategies aim to reduce the cognitive load associated with managing multiple threads and channels. By refining communication habits, users can foster a more productive environment, focusing on what truly matters in their roles. The author emphasizes that small improvements can lead to significant long-term gains in efficiency.
