Humanity Labor are an employment agency and union, with political ties and a political agenda. They are dedicated to getting humans into jobs, typically blue-collar or casual jobs, something which has become almost impossible as bioroids and clones take those positions in their thousands. Humanity Labor is in no way affiliated with the extreme political group Human First, although it is a free country and members of Humanity Labor are free to join whatever political groups they see fit.
Their offices are in central New Angeles. If you're looking for someone to do a job, no questions asked and no pesky paper trail, that's the place to go. That includes black-ops and wetwork, if the price is right. The NAPD categorically denies any of its agents would hire third parties to close cases with murder, whatever Lily Lockwell might allege.
