The Challenge

The thrift store chain's HR department was overwhelmed by repetitive queries from 45 branch locations. The 3-person HR team was spending most of their time hunting through hundreds of policy documents, employee handbooks, benefits guides, and compliance materials to answer routine questions about vacation policies, dress codes, performance reviews, and disciplinary procedures.

With documentation spread across shared drives and outdated folders, HR responses often took 24-48 hours, frustrating branch managers and delaying critical decisions. The manual process also made it impossible to identify gaps or inconsistencies in company documentation, leading to conflicting guidance across locations.

Our Solution

We developed an intelligent HR chatbot using RAG (Retrieval-Augmented Generation) technology that indexed the company's entire documentation library.

The system allows HR staff to instantly query company policies using natural language, receiving accurate answers with source citations. The chatbot serves as both a response tool for employee queries and an analytical engine that tracks frequently asked questions to identify documentation gaps. The system flags outdated policies, highlights contradictory information, and provides insights into which topics generate the most confusion, enablingthe HR team to proactively improve their documentation strategy.
