Mercor's CEO says Gen Z's frequent job changes undermine long-term growth, citing lost equity and trust. Data shows 2-year 3-month average tenure. Andreessen Horowitz partner offers counterpoint.
Mercor's Brendan Foody thinks Gen Z is moving jobs so often that they are sabotaging their own careers.
The 23-year-old CEO of the AI-training company posted on X that he was surprised by the short average tenure he sees among younger candidates he interviews. "Too many people in my generation underestimate how much relationships, reputation, equity, and trust compound over time," Foody wrote Monday.
Instead of building long-term ties, these workers "jump to the hottest company every year because they think it looks good on a résumé," he said. "Look at almost anyone who's built something extraordinary: they weren't serial job hoppers."
The data backs up the perception. A 2021 CareerBuilder analysis found Gen Z workers spent an average of 2 years 3 months in a role, six months less than millennials. A 2023 Oliver Wyman study reported that 70% of Gen Zers in the US and UK who said they were "loyal" to their employers were still looking for a new job.
Andreessen Horowitz partner Josh Elman replied to Foody's post with a qualifier. "You are right that going from job to job without meaningful contributions nor closure is a bad pattern," Elman wrote. "It is worth going deeper with people who continue to work on important things at important times. That perspective compounds."
In an email to Business Insider, Foody said workers should change jobs for the "right reasons," such as when they stop learning. "Moving because the work is better is very different from moving because a logo looks good on a résumé," he wrote.
Job-hopping can boost pay quickly. Changing companies has often led to faster compensation growth. Foody acknowledged that. "Switching jobs can often be the fastest way to get a raise or a title bump in the near term, so the incentive feels real," he said.
Still, many workers are now "job-hugging" – staying put for stability after a tough hiring stretch. The term reflects a shift from the earlier pattern of frequent moves. Foody, based in San Francisco, noted that compensation there is climbing fast, especially in AI. "Everyone knows who just raised, who's hiring, and what the offers look like, so the grass always looks greener," he wrote.
Gen Z is not the first generation tagged as job-hoppers. Millennials held that label before them. Data from the Bureau of Labor Statistics showed neither generation was the most likely to change jobs at age 20, however. (Note: The original BLS data compared cohorts; at that age, earlier generations actually moved more.)
The cost of frequent job changes for young workers goes beyond lost equity. Each move resets the clock on vesting, on mentorship relationships, and on the informal trust that builds with longer tenure. For companies, high turnover among early-career employees raises hiring and training costs, and it reduces institutional knowledge. The economy may see a longer ramp to peak productivity if workers delay settling into roles where their experience compounds.
Foody offered a straightforward test for whether a move makes sense. "If the new role lets you learn more, build deeper skills, and work on harder problems, it's probably the right one," he said. "If you're just chasing a logo or a base salary number that looks slightly better, you'll likely regret it in a couple of years."
