Workforce (Star Trek: Voyager)

[1] On an alien planet, Kathryn Janeway happily shows up for her first day of work at an energy plant, eager to take up her new position.

The ECH explains that the ship was damaged by a floating mine, which was a ruse allowing unknown parties to abduct the crew.

A young doctor begins to become suspicious of so many people of the same species having the apparently rare "dysphoria syndrome," and almost all of them getting jobs at the energy plant at the same time, and none of them having any previous file references.

After gentle inquiries result in an official "hands-off" warning from local law enforcement, the doctor approaches Annika Hansen, who is initially skeptical, but begins taking Tuvok's rants seriously.

Examining the files of the plant's newest "employees," she discovers they are all Voyager officers and crew, and begins to launch a deeper investigation.

Working with the plant's doctor and a suspicious investigator, Annika unmasks the conspiracy while Chakotay convinces Janeway and Jaffen to help.

With the conspiracy exposed, the planetary government promises to stop the forced labor practice and return everyone who was abducted home after reversing the conditioning that they had undergone.
