Headcount reduction, division later profitable
Restructuring · Texas Instruments

A money-losing division had to cut headcount by 20%. The usual practice was same-day notice and a walk-out.

What I did. Proposed and ran a new approach: 60 days' notice so people could interview for open roles across TI, an all-hands on what, when and why, and 1:1 support for every impacted employee.

Result. No lasting damage among those who stayed; the division restructured and returned to profit, and many impacted employees found new roles inside TI.

−68%
Lost-time injury frequency
Safety · Epiroc

As VP of HR and SHEQ, I owned a division-wide injury rate that had to come down.

What I did. Shifted the division to proactive safety measures and ran the “Why I work safely” campaign.

Result. LTIFR down 68% and TRIFR down 45% since 2023, with three injury-free months in 2025.

$760M
STANLEY Infrastructure acquisition
M&A · Epiroc

Epiroc's $760M STANLEY Infrastructure acquisition (2024) brought in about 1,380 employees with a 60-day Transition Services Agreement.

What I did. Led the stand-up of payroll and benefits, including a new 401(k), then led health plan harmonization and the 401(k) harmonization roadmap.

Result. Payroll and benefits live inside the 60 days; health plans harmonized for 2026.
