A lot of the employees walked out while on their shift in the hopes of getting Glenn his job back. The regional manager has arrived and is working with Jonah and Amy to see how they can get the employees back to work. Initially, Amy and Jonah ask only for Glenn to have is job back, but they must sign a letter saying that they apologize for walking out. While it seems like a small request, they decide that the employees really deserve more. Part of the goal of unionization is to turn a competitive labor market into a monopoly provider of labor. Through collective bargaining, Amy and Jonah demand more for their group.
When Mr. Pulitzer decides to raise prices in the distribution channel by forcing the newsies (the newspaper boys) to pay higher prices for a pack of 100 papers, the newsies decide to go on strike. Without raising the price to the final consumer, the price increase essentially just lowers the profits the newsies can collect. They decide to go on strike and create a newsies union to have more monopoly power in the process.
