31 years at Microsoft, then a layoff: what tech workers' regrets say about retention

Mike Kostersitz, now a senior director of product management at Nike, spent 31 years at Microsoft before being laid off last year, and he told Business Insider his biggest career regret is not moving on more decisively before that happened ^[1][2][4]. The other regrets published alongside his point the same way, which makes this less a story about one person's timing than a read on how employees now price the loyalty managers still count on.

Kostersitz, who is in his early 60s and lives in Oregon, said he stayed loyal to a company that had been good to him since the 1990s, believing that sticking it out would be reciprocated ^[3][5]. His summary: "the market shift hit me anyway, loyalty or not" ^[6]. Given the chance again, he said, he would have started testing the market well before the business yanked the carpet out from under him ^[7].

Nikhil Singh, a data scientist at Amazon in his 30s, named the same problem at an earlier stage ^[8]. He spent more than a decade building products and very little time writing, speaking or contributing to the wider industry conversation, and said what he underestimated was that outside your own organisation you can be seen "as simply another person with a title on LinkedIn rather than someone with meaningful expertise or a distinct point of view" ^[9][10]. A Meta software engineer's regret is a bet on a field rather than on an employer: he built machine learning models at an edtech startup in 2019 and 2020, then chose systems and infrastructure in graduate school because it felt safer and more rigorous ^[11][12]. Across the full group of ten, Business Insider reported regrets including not leaning into AI sooner, turning down a job offer, staying too long at one company, and waiting too long to build a professional reputation in the broader industry ^[15].

Of the five accounts carrying detail, three are about standing in the external market, one is about backing the wrong technical field, and one is about conduct and documentation inside a company ^[13][14][17]. None is about leaving an employer too soon ^[18].

The caveat matters: this is ten self-selected people talking retrospectively to a reporter, with answers edited for length and clarity ^[16]. It measures nothing. What it describes is an asset that managers still present as a benefit and that at least these employees no longer treat as one. Tenure did not function as protection in Kostersitz's account, and he says so plainly ^[6].

That changes the shape of attrition risk. Decay does not start with a resignation letter; it starts when a strong performer begins publishing, speaking and answering recruiter mail while doing the same job at the same desk. Singh's regret is precisely that he did not start doing that sooner ^[9]. The version of that person who takes his own advice is still on your payroll and is also a year into making departure cheap.

Watch the tells that are not resignations: external writing and conference talks from people who never used to do either, requests for customer-facing or public work, sudden interest in being quoted. Then check what your retention pitch actually offers beyond more years in place. Kostersitz's 31 years and a layoff notice is the version of that pitch employees have already heard ^[2].
