Parapundit Randall Parker had an excellent blog post about the Amazon.com warehouse where workers “were routinely sent to the emergency room because of sweltering, suffocating heat.”
The part about how the managers refused to open the doors for ventilation because they were worried about employee theft reminded me of the Triangle Shirtwaist Company locking the fire exits to prevent employees from sneaking a break.
What the 1910s and today have in common is that they were both times when there were a large number of immigrant workers in the United States. Today, the foreign-born population is the highest since 1920. Cheap immigrant labor lowers the value or workers and how companies treat them.
