The leadership read

A change at the top rarely stays at the top. Sisk's move reshapes the layer beneath it in the sector as a new leader sets priorities and the team re-forms. Watch the first two or three appointments that follow; they signal direction more reliably than any statement.

Market context: This lands while the Talent Market Index reads 109 (Hot) — up 7.3 versus the prior month — and EMEA signal share is easing (-3.1pts).

Sisk: 1 signal in the last 90 days.
