Final answer:
The worst part of working conditions is the struggle of low-wage workers to survive on minimum wage, which results in multiple jobs, untreated health issues, and unsafe working environments needing improved labor standards.
Step-by-step explanation:
The treatment and working conditions of low-wage workers seem to be the worst part, where it is almost impossible to survive on minimum wage.
The experience described where employees must work multiple jobs, live in substandard conditions, and still struggle with untreated health problems, indicates a system that fails to support its most vulnerable members.
Moreover, the physical and mental toll of such working environments, including chronic illnesses from poor conditions and injuries from unsafe practices, highlights the urgent need for better labor standards.
