Internal Mobility and Changing ESN: When to Leave, When to Stay
As of 2026-08-16
Internal mobility and ESN-switching decisions conflate two different premiums, and the Employee Salaries study separates them. A structural gap is real and persistent: T4 ESN runs 5-12% below T3 Global SI at every French grade (Part IV.5). A transient premium is real but temporary: the 2024-2025 Atos restructuring produced a EUR10-25K lateral-hire premium the study explicitly flags as unlikely to persist past 2026. The Employee Consultants study's bench-risk calendar (Part X.3) and park-signal proxies (Part VII.1) give a concrete trigger for when to open the conversation, and the comp-inversion synthesis (Part VII.6) frames Y5-Y10 as the canonical decision window.
What you will learn
- Distinguish a transient dislocation premium (like the 2024-2025 Atos restructuring) from a structural tier gap.
- Quantify the T4 ESN vs T3 Global SI structural compression at your own grade.
- Read your own park signals before deciding whether to open an external conversation.
- Map a stay-or-move decision to the Y5-Y10 comp-inversion window rather than deciding on instinct.
Internal Mobility and Changing ESN: When to Leave, When to Stay
The transient premium is real, and it is transient
The Employee Salaries study (Part IV.5) documents a concrete case: Atos's 2024-2025 restructuring (the Atos/Eviden split, widely covered in financial-distress headlines) degraded its SAP practice's competitive position against Sopra Steria and Capgemini France. Consultants moving laterally from Atos to Capgemini France or Big-4 France were typically paid EUR10-25K more in total cash at lateral hire — a market-clearing effect the study explicitly flags as unlikely to persist past 2026 once the restructuring stabilises. If you are sitting on a similar dislocation today, the window to capture it is now, not in eighteen months.
The structural gap that does not go away
Prerequisites
- At least Y3+ tenure inside an SAP analytics employer, with visibility into your own utilisation and sponsor history.
- Review core concepts first: C047, C150.
Outcomes
- State the current ESN vs Global SI structural gap at their own grade.
- Identify whether a lateral premium they are seeing is structural or transient.
- Run the two-signal park-risk self-check before opening an external conversation.
- Apply the Y5-Y10 decision window to their own tenure and skill combination.
