Case Study: TalkTalk achieves HR transformation and 90% user adoption with Workday Adaptive Planning

TalkTalk provides its people with a consumer-grade employee experience

TalkTalk, a leading UK telecom serving about 4 million customers, had grown through acquisitions and was held back by fragmented, outdated HR technology. Manual recruitment processes, limited self‑service and poor manager visibility made HR transactional and inefficient, undermining the desired consumer‑grade workplace experience.

TalkTalk performed a “big‑bang” Workday rollout—deploying HCM, Recruiting, Time/Absence, Compensation, Benefits and Talent across 2,500 workers with 13 integrations (including ADP), consolidating seven legacy systems. Within a month >90% of users had logged in; time to hire fell 10%; Workday became the single source of HR truth with real‑time insight and near‑perfect payroll accuracy, freeing HR to spend roughly 65–70% of its time on strategic work.
