💪 Resilience is more than a mindset—it’s a muscle we build together.
At our company, resilience means showing up with empathy, adapting to change, and supporting one another through uncertainty. It’s how we stay grounded, grow stronger, and keep our culture thriving—even when the road gets bumpy.
In this quarter’s newsletter, our VP of HR, Darcelle Wilson, shared how resilience shows up in HR—and why it’s essential for every part of the organization.
We’ll be sharing more insights from the newsletter over the next few weeks. Stay tuned!
