Interviewer instructions
Enter the appropriate code for the length of time that the person has been doing this sort of
work. When counting the number of years that the person has been doing this sort of work,
include all the years doing this sort of work, both for this employer and for any other employer
(if any). For instance, if the person has done this sort of work for four years for their present
employer, and they did similar work for two years for a previous employer, this makes a total
of six years, which should be coded as ‘3’.
