Craving work-life balance is a huge red flag, says Fortune 500 CEO—and like Barack Obama, he happily works through the weekends

While millennial and Gen Z workers consistently rank work-life balance as their number one priority, Iñaki Ereño, the chief executive of one of the world’s largest healthcare companies, says if you’re obsessing over balance, your problem isn’t the hours. It’s the job. “When the balance of your life becomes a topic, then you have a problem,” Ereño exclusively told Fortune . “You need to like your job, to not feel that your life needs to be balanced.” Essentially, in his eyes, needing to separate work from life with a hard 5 p.m. cut-off doesn’t make sense when you genuinely love what you do. So if you’re constantly counting down the hours to the end of the day, it’s probably a sign that something fundamentally isn’t clicking.

The Fortune 500 CEO’s strict daily routine When Ereño’s not running a multi-billion dollar healthcare group, he is, by his own admission, still very much in work mode. Just not in a way that feels punishing to him. He starts most mornings around 6:30 a.m. with a black coffee and six newspapers—three in English, three in Spanish—on his iPad before jumping on the tube (Britain’s subway) to …
