What is the author's style in Trouble in Mind by Alice Childress?

Trouble in Mind focuses on the rehearsals for a Broadway play, Chaos in Belleville. In Chaos, Job (played by John) is a young man living in the South who has been called up for military service. He wants to vote, and his actions in this matter lead to a lynch mob coming after him. His family work as sharecroppers. His mother Ruby (played by Wiletta) sends him to his death, believing a lynch mob will show him mercy. Sheldon plays Job's father, Sam, while Millie's character is named Petunia. Some members of this family work for the white Renard (played by Bill O'Wray) and his daughter Carrie (played by Judy). Renard and his daughter treat the blacks as lessers, like children who need the guidance of whites. Renard offers to house Job in jail to protect him, and Ruby lets him go, which ultimately leads to Job's death.
