What’s the Biggest HR Mistake Companies Make During M&A?

Episode Overview

When most people picture Merger & Acquisition, they picture spreadsheets, valuations, deal structures, and closing timelines. But ask anyone who's actually lived through a merger or acquisition, and they'll tell you the deal that looks perfect on paper can still fall apart because of what happens to the people inside it.

So in this episode, we're looking at M&A from the workforce side, the part of the deal that rarely makes the press release but almost always decides whether the deal actually works. And to help us, we have with us Elizebeth Mack, Principal and Workforce in Transactions Leader at BDO USA.
