In To Kill a Mockingbird, Chapter 27, explain how Mr. Ewell lost his job and whom he blames.
After the trial, Bob Ewell got a job working for the WPA. The WPA (Works Progress Administration) was a government program under President Franklin D. Roosevelt whose purpose it was to provide jobs for the unemployed during the Great Depression. Scout explained how it occurred:
... Mr. Bob Ewell acquired and lost a job in a matter of days and probably made himself unique in the annals of the nineteen-thirties: he was the only man I ever heard of who was fired from the WPA for laziness (To Kill a Mockingbird, Chapter 27).
Before getting the WPA job, Bob Ewell had not worked at all. Instead, he lived on his weekly welfare check. After being fired from the WPA, Bob Ewell went right back to collecting his check and not working. His lack of work ethic had been evident when he got fired for laziness. Despite this, Bob Ewell blamed Atticus. He told Miss Ruth at the welfare office that Atticus had gotten him fired, though it was an untrue statement.
Incredibly, Bob Ewell actually got a job in Chapter 27 of To Kill a Mockingbird. However, it didn't last long. In fact, Scout notes that Bob
probably made himself unique in the annals of the nineteen thirties: he was the only man I ever heard of who was fired from the WPA for laziness.
The WPA (Works Progress Administration) was one of President Franklin Roosevelt's New Deal job programs that created public works jobs for the unemployed. Bob immediately began collecting his welfare check again, but not before slurring Atticus in the process. According to Ruth Jones, the welfare lady, Bob blamed Atticus for "getting" his job, though there is no clear reasoning behind the accusation. and Scout provided no clues. It may well have had something to do with Bob's innate lack of desire to do any kind of hard work.
Mr. Ewell had gotten a job with the Works Progress Administration. This was a New Deal program that was meant to give people jobs to help end the Depression. When he loses his job, he blames Atticus Finch and sets out to get revenge on him.
Mr Ewell, Scout tells us, is the first person ever to actually lose a WPA job because of being too lazy. She says that she thinks that he worked hard for a little bit, but then went back to his normal ways and that is why he lost his job.
