What is the author's style in Waiting for Lefty by Clifford Odets?

Odets specifies that Waiting for Lefty is enacted on "a bare stage." Whether the setting is a union hall, an office, or an apartment, there are no furnishings to help establish the scene The full stage— extending into the audience—represents the strike meeting. For the "flashback" scenes that tell the stories of various individuals, simple lighting effects are used to create small, intimate playing spaces onstage. Such stark, relatively undefined staging is not uncommon, and "minimalist" dramatist.
