I think there are a lot of fires. Here is a query for "Structural Fires" classified as "Other commercial building fires" in NYC, during the month of March 2025 (excluding simultaneous calls): Fire Incident Dispatch Data | NYC Open Data

There are 342 entries, a bit more than 10/day. There isn't any way to directly filter more specific than that (for warehouses/retail), but it's also just one city. Being designated as "commercial" implies the location is a workplace. So I guess we can imagine each of these as a spark of rebellion???

Most acts of workplace sabotage are not grandiose; there is nothing to put on tik tok. People know how to fuck with their employer in a way that keeps themselves and their communities safe.

It's very stupid to even fantasize about a trend of angry workers starting fires like this. For goodness sake, the more neglient and avaricious the employer, the laxer attention to safety, the less likely everyone is to get out alive and safe. Nobody here even knowing the triangle shirtwaist or anything? Industrial fires (however they start) are often catastrophes for working class people.
