I don't see people talking about this so today is the 110th anniversary of the Triangle Shirtwaist Factory fire, in where the factory owners locked working women and girls inside to "eliminate the risk of theft" (in reality it was too keep them from taking breaks), which resulted in the gruesome deaths of 123 mostly immigrant women and girls and 23 men, many of whom jumped to their deaths from the ninth floor either in a panicked attempt to escape or in order to die quickly. There were reports that some of the workers were on fire already as they jumped.
The eighth floor of the building was able to telephone the tenth floor to warn them about the fire, but the factory on the ninth floor where these women and girls labored had no such communication and such warning.
The factory owners were criminally charged with manslaughter for actions that contributed to the mass deaths but acquitted. However, this tragedy led to mass sympathy to the labor movement, and unions spurred on safety regulations that passed in New York state and eventually the entire country, and activists were able to reduce child labor in the process.
This tragedy is a reminder that has been forgotten in the 110 years since: every safety regulation-- every scrap of paperwork contributing to the hundreds of pages of red tape people like to complain about--every word of it was written in the blood of a laborer.
111th anniversary
They were discouraged from breaks because they were actively trying to unionize, and bosses felt that keeping them from unsupervised contact would prevent them from joining the garment workers' union.
This is why unions are important. This is why today, right now, the biggest companies in America are trying to squash unionization of their laborers and why those workers are fighting so hard to unionize.
@tikkunolamorgtfo did a great write-up a few years ago about the aftermath of the Triangle Shirtwaist fire, and I highly recommend reading it (and anything else you can about the fire). It is painfully relevant still and it's incredibly important women's, Jewish, immigrants', and workers' history.
