Ark Workers were the Chinese people who worked on building the arks in Tibet to ensure that the humanity survives. The only know ark worker was Tenzin. Carl Anheuser mentioned that if Adrian Helmsley wants to sell his ticket to a random Chinese guy, then he was free to. The Chinese goverment didn't bother about the ark workers. Most of the ark workers survived the apocalypse when the gates of Ark 4 opened.
