It looks like it's a questionnaire through the Current Population Survey (https://www.census.gov/programs-surveys/cps/technical-documentation/questionnaires.html https://www.census.gov/programs-surveys/cps/technical-docume...) and the wording I found: (THE WEEK BEFORE LAST/LAST WEEK), did (name/you) have more than one (job/job or business), including part time, evening or weekend work? So it doesn't look like it separates different kinds of work.
