The most layoff-prone job in tech right now Sean Anthony Eddy/Getty Images Coinbase and other tech companies want fewer managers — and ones who can act as "player-coaches." Managers who don't do any individual contributor work are especially vulnerable. Those who survive layoffs are being tasked with overseeing AI agents — and more workers. Managers who don't produce are becoming expendable. As tech layoffs roll on and org charts flatten, some industry leaders are sending them a sharp directive: Keep tabs on your reports, but be sure to contribute, too. In a letter to Coinbase staff on Tuesday, CEO Brian Armstrong announced plans to lay off 14% of its workforce and said everyone at the crypto company must be "a strong and active individual contributor." He also said the changes mean teams will be smaller — in some cases, just one person and their AI agents — and that there will no longer be "pure managers." Sound familiar?…
