Zapier`, a workflow automation tool, helps knowledge workers ease the transition from vacation to work by automating tedious tasks through pre-made workflows called Zaps. These workflows send information from one app to another, allowing users to focus on more meaningful work. Zap templates can be used to filter emails and messages by importance, gather project progress, send company announcements, notify team members about priorities, and create an out-of-office repository. By utilizing these features, users can quickly catch up on missed work without having to read every email or message, making it easier to return from a vacation.
