Show in the "OCC YRS" block the number of years that the claimant worked in the customary
occupation, if determined, or, if not determined, in the longest full-time occupation.
NOTE: When such information is not reflected on the SSA-3369-BK it may appear elsewhere
in the file.
Where there are broken periods of employment in that occupation, determine the total
number of years the individual was employed in the shown occupation. If the number
of occupational years is unknown, enter "unk" in the OCC YRS block.
