Sidebar is a modern collaboration feature within the Next Experience user interface that allows HR agents to communicate with other agents or stakeholders in real-time directly within the context of a record. Unlike Work Notes, which are primarily for asynchronous documentation, Sidebar provides a " chat-like " experience for immediate troubleshooting and knowledge sharing. This is particularly useful for complex HR cases that require input from different specialists, as it keeps the conversation linked to the case record for future reference while allowing for the rapid exchange of information. Sidebar represents the evolution of agent collaboration in ServiceNow, replacing older tools like Connect Chat with a more integrated, Workspace- compatible solution that aligns with the multi-tabbed productivity requirements of modern HR Service Delivery.
