Links to Some Resources
When I began this research, I looked for any links related to on-boarding and off-boarding processes in newsrooms. In the survey, many people I interviewed sent me their newsroom's files/guides if they had any, but because they contain information that may be private, I can't link to them.
Here are some places that included the most thorough information on their on-boarding and off-boarding processes.
