Like, to be fair, this was literally 10 years ago. You really gotta dig up some old stuff to find examples of Nintendo lay-offs, and they certainly don't happen at the mothership NCL in Japan, which is where nearly all research and development takes place, and where the vast majority of Nintendo staff are located.
All examples of regional offices laying off staff are mostly agency workers too, so many of them weren't even Nintendo employees. Yes, still a layoff, but not quite the same thing. Another more recent example would be the minor reorganization at NoA after they closed the California office in Redwood at the end of 2022. But that was a COVID-driven thing. Nothing to do with poor sales or performance, or lack of money coming in.
Back in 2014 when this minor reorganization took place at NoE, Nintendo was in the midst of losing hundreds of millions of dollars per year due to the Wii U business, and Iwata and the executive staff all took salary cuts. Had they not done that, very uncommon layoffs like this numbering in the low hundreds would have been more like in the thousands. Nintendo very rarely ever does lay-offs, and even more than that, any other company experiencing $200 million losses 3 years in a row would've laid off way more than this.
