“In reality, she will only ever be the Twitter COO for Musk; at worst, Musk’s executive PA,” my colleague Lila MacLellan quoted one PR expert as saying, when trouble was brewing a few months into the job.

Certainly Yaccarino is not the first leader to be overshadowed by a powerful boss. I’ve spoken with many over the years, from Jeff Immelt when Jack Welch delayed his exit from GE by a year to work on the Honeywell deal, to former CEOs at brands like Disney and Starbucks where a former boss boomeranged back without ever truly exiting stage left.  

I spoke with some experts this week about the unique challenges of being in such situations and how best to handle them. The first step is to set clear expectations and boundaries so that you have an option to leave with your reputation intact, CEO advisors told me. 

You try to build trust and may have to tolerate sharing the spotlight with a predecessor who continues to linger down the hall. (A familiar refrain in some family-owned companies.) “It’s okay if the founder has a voice on certain topics. But if everyone still looks to the predecessor for leadership, that’s a problem,” Constantine Alexandrakis, CEO of Russell Reynolds Associates said.

And if it doesn’t work out, you can either quietly leave or write a book about what you did and faced during your time at the helm. Though, as one ousted CEO told me recently, “the problem is there’s always a nondisclosure where you can’t set the story straight.”

From the analysts

Macquarie on the Brazil tariffs: “Traders thought that Brazil was 'marked safe' from aggressive President Trump's reciprocal tariffs because the US runs a merchandise trade surplus with Brazil. Yet the US just placed a very aggressive 50% tariff on Brazil's exports to the US, citing how Brazil's president was treating his political rivals, among other things. … The action against Brazil sets a scary precedent, insofar as it is the first time that Trump's tariffs are intended to influence (ostensibly) a country's internal political and judicial settings,” per Thierry Wizman and Gareth Berry.

Pantheon Macroeconomics on the labor market: “We continue to expect the unemployment rate to rise more quickly in the second half of this year than the FOMC expects. Labor demand is continuing to decline; for instance, Indeed’s measure of total job postings has fallen a further 1% in the month to July 4, extending the drop since the end of last year to 5%,” per Samuel Tombs.

Wedbush on Nvidia and Microsoft: “We believe Microsoft will also hit the $4 trillion market cap club this summer and then over the next 18 months the focus will be on the $5 trillion club....as this tech bull market is still early being led by the AI Revolution,” per Daniel Ives et al.
