How does the author use foreshadowing in Anna in the Tropics?

Anna in the Tropics portrays the lives of cigar factory workers in Ybor City, Tampa, Florida, when a new lector, perhaps the last to ply his trade, is hired. The men and women remain divided in their loyalties as economic hardship and the pressure to abandon old traditions force the owners of the cigar factory to adopt new, progressive manufacturing methods if they wish to stay in business.
