Final answer:
Janie's frustrations at work include the impossibility of living on minimum wage, the extreme measures needed to survive, and the poor treatment and lack of appreciation for low-wage workers.
Step-by-step explanation:
Janie's frustrations with working at the store, as portrayed in the book TEWWG, largely revolve around the economic and social difficulties associated with minimum wage work. She discovers that surviving on such low wages is nearly impossible, which leads her to understand the struggles that many working-class individuals face daily. Janie observes her fellow employees going to extreme measures to make ends meet, such as holding multiple jobs, working without breaks, living in inadequate conditions, and struggling to afford healthcare. The poor treatment of low-wage workers is a significant aspect of her frustration, as she witnesses disrespect and a lack of appreciation for the hard work that she and others put in.
