ELI5:How does the witness protection program work?

Specifically, how severe does one's experience have to be to be submitted into the program. Is it voluntary? Do you get totally shut out from all friends and family?

They take the person and their family and find another area in the country to work, change their name, and find them a job under that identity. All contact to their former life is cut.

No person in the program who does this has ever been found. People are only found if they decide to retain some contact with people they knew.
