Parking Lot Attendants -- Sit-Stand Option?

Some variation of light unskilled work with limitations on standing/walking and even a sit-stand option (SSO) will frequently get a vocational expert to identify parking-lot attendant. The free DOT-SOC/O*NET Crosswalk from www.occucollect.com lists three DOT codes in the group:

53-6021.00-Parking Lot Attendants

The list of DOT codes suggests that all the jobs are light, but that is not true.  The DOT lists typical performance, not maximum performance.  SSR 00-4p is wrong and does not survive application of Kisor v. Wilkie.  The quest involves proof of the strength and skill requirements.

The Occupational Requirements Survey reports:

The mean suggests that the average parking lot attendant requires medium exertion because the worker lifts/carries more than the maximum of light work, 20 pounds.  We also can find that most of the jobs are indeed unskilled.  

Series ID: ORUV1000065A00000065

And there, the ORS runs cold.  To determine the availability of light work, we must resort to the O*NET OnLine.

The majority of parking lot attendants walk/run all day long.  Potential for an SSO exists only in those jobs that permit sitting continually or almost continually.  That is how labor defines the SSO. Because of the lifting, some of those jobs might be sedentary.  Now we turn to the number of jobs reported by the Occupational Outlook Handbook:


53-6021 - Parking lot attendants

Typical Education Needed
No formal educational credential
Work Experience in a Related Occupation
None
Typical On-The-Job Training Needed to Attain Competency
Short-term on-the-job training
2018 Employment
150,700

We erode the 150,700 jobs by the number that are unskilled, 84.3% of the jobs, and get 126,588.  The O*NET reports that 81% are full-time, lowering that number to 102,536.  We now apply the percentage of jobs that are reported as sitting continually or almost continually in an eight-hour day, 18%, and get 18,456.  

The 18,456 number of jobs includes both sedentary and light jobs.  Without better data, further exploration of that division is not possible.  We can point to the broad description of Transportation and Material Moving Occupations (53-0000.00):

Series ID: ORUP1000048P00000661
Not seasonally adjusted
Series Title: % of workers in transportation and material moving occupations; strength is sedentary
Requirement: Physical Demands
Occupation: Transportation and Material Moving Occupations
Estimate: strength is sedentary
YearPeriodEstimate
2018Annual11.2

The proposition that some or most of the sit down parking lot jobs is sustainable.  Of course, the question is whether the vocational expert has a reliable methodology that beats cold application of statistics.
