In 2026, "Strengthen Sickness & Wellbeing Management" is a top-tier People Strategic Priority for Booking.com. Following 2025 operating model changes, this program is focused on recovering productive capacity and embedding accountability across the organisation. We are seeking a senior-level HR professional for a hands-on assignment through the end of the year to execute critical workstreams within this strategic program.

Role Purpose Working directly for the Program Leads (Eline Snabel-Steinmetz & Boaz Saam) and in close collaboration with the Program Manager, you will take ownership of delivery of key projects. You will provide the "boots on the ground" necessary to move from strategy to operational reality, ensuring our sickness management infrastructure is robust and future-proof.

• Operating Model Transition: Support the practical shift between the new model and daily reality. Align support layers to ensure all cases are handled at the right level while strictly avoiding double work.

  
  

• Process Refinement: Identify and fix friction points in our internal sickness processes. Refine workflows to ensure support is placed in the right layer—balancing manager accountability with enhanced back-end support—to keep cases moving forward.

  
  

• Operational Execution: Beyond project management, you will handle the necessary "heavy lifting"—from drafting internal communications and guidance to supporting regular updates, providing data and employee support materials.
