UKG (formerly Kronos and Ultimate Software) is a multi-billion-dollar horizontal HR, payroll, and workforce management vendor. It runs traditional shift work well. It was not built for a flexible clinical workforce — and the gap shows up as manual work.
UKG Dimensions schedules fixed shifts with manager-configured rules. Multi-license, multi-region, multi-skill clinical teams — with FTE, part-time, contractor, and agency staff — fall outside that model, so operations teams compensate with spreadsheets and bolt-on tools.
Time off, on-call, swaps, and data entry stay manual or require additional software. Untether's AI executes that work end to end and auto-builds schedules to hit patient SLAs and provider preferences.
We replaced UKG at Dialogue, Canada's leading hybrid care provider, with one AI-first system — automating scheduling, time off, and payroll submission across 13 regions, and upleveling the operations team instead of expanding it.
Yes. We replaced UKG Dimensions end to end at Dialogue — scheduling, time off, time cards, and payroll submission — across a flexible, multi-region clinical workforce.
UKG is horizontal HR and payroll built for fixed-shift work. Untether is AI-first workforce management built for clinical teams, with auto-scheduling, demand forecasting, and license- and credential-aware coverage.
Untether automates scheduling, time, and time off and submits to payroll, integrating with your HR and payroll systems rather than replacing your system of record.
UKG can be the right call if horizontal HR is the priority.
Untether fits if scheduling your clinical teams is the hard part.
