In the future, Big Business owns the government. Corporations such as Target, Walmart, General Motors, etc... now have a major hand in deciding policies in the country. This has a major impact on how workers are viewed by their companies. A law called SEDWA (Shameless Exploitation of Dead Workers Act) has passed, which most big companies have taken advantage of.
An employer has the right to resurrect a person after death for continued service to that company. This is part of the contract that this soon-to-be corpse, better known as an "employee", signs when hired. When a worker dies after a lifetime of being nickled and dimed, their body is resurrected for further servitude to the company and put back to work. This ensures that the corporation gets the full mileage out of their workers. The process has been active for several decades, and the Zombie work force is a common sight in many kinds of jobs.
This resurrection process is not cheap, so only big corporations can justify the expense. These zombies cannot follow complex commands and are relegated to performing unskilled labor. However, they are the perfect example of what a good employee should be. They don't eat co-workers, are obedient, are able to work 24/7, don't bitch and moan about work safety or ask for pay, and are cheap to maintain due to not being affected by decomposition. Even better, they don't violate the fair labor standards act set in place by those annoying and ridiculous labor unions, which demand a minimum wage and 40 hr working weeks on account of the person already being dead. It's a win-win from the employers perspective!
The problem I have here is that I don't know if the process of resurrecting these workers and binding them to eternal servitude would be worth it to the employer in terms of cost effectiveness. What estimates do I need to take into account to make this plan marketable to corporations? Is it economically viable?
