Mail Clerk and Six Hours of Standing/Walking

Marian Marracco testified at a hearing yesterday.  Marracco has a bulk provider agreement to testify before the Social Security Administration as a vocational expert.  She was in New Jersey.  Now she works out of Desert Hot Springs.  She is prolific.

The ALJ directed Marracco to assume an ability to perform light work as defined in the regulations with other limitations.  Marracco identifies three occupations:  night cleaner; mail clerk; and garment sorter.  On cross-examination, the question turns to the medical expert's testimony: six hours of standing and walking in an eight-hour day.  Marracco says no change because the DOT defines light work as six hours of standing/walking in an eight-hour day.  Marracco further testifies that no light work ever requires more than six hours of standing/walking in a day; no light work requires standing/walking throughout the day; and Labor does not have data to the contrary.  We covered the DOT, regulation, and ruling in the preceding piece on this blog.  We turn our attention to mail sorter or mail clerk.

Marracco used DOT code 209.687-026.  Occu Collect confirms that Labor puts this occupation in maids and housekeeping cleaners (SOC 43-9051).

Given the breadth of the occupational base, my confidence level of mail sorter represents more jobs than all 14 mail clerks and mail machine operators is low.  Moving right along to the O*NET OnLine:

Given the disparity of sitting, standing, and walking suggested by the O*NET, the average is meaningless.  We need the percentiles.

The hours of standing/walking at the 25th percentile is standing/walking four hours per day.  The demands at the 50th percentile is 6.3 hours per day.  A person limited to six hours of standing/walking in a day can perform more than 25% but less than 50% of the jobs.  Mail Clerks have a sit-stand option in 38% of jobs making that a probable point for demarcation.  The percentages of the day, 90% at the 50th percentile and 74.9% of the day at the mean bolsters that deduction.  

Nor are a plurality much less a majority of these jobs in the light category.  Mail clerks engage in medium or heavy exertion in at least 57.1% of jobs.  Mail clerks engage in heavy exertion in at least 10% of jobs.

Unlimited standing/walking in the context of light unskilled work yields 13,037 full-time jobs in the economy.   If limited to six hours of standing/walking in a full-time day, then the person can perform fewer than 5,000 jobs.  .
