Respectfully, Steve, I think it might be 7 plus another adjuster to drive the pick up truck (minimum charge) to dispose of the bulb since the first one has ongoing mitigation duties associated with the residence, or 8 if you need someone to bring the 40 cubic yard container for disposal if its a pretty big bulb.
Somewhere you also need more adjusters to handle the matching problem since not all of the bulbs will look the same from the same elevation once you change one bulb since most Texas adjusters know that we owe to match. Then, there are going to be workman's comp issues related to the burns that are no doubt going to occur for changing multiple bulbs since 1) this is a slow time, and 2) unemployment does not last long, but 3) workman's comp injuries can be real gold mines for things like burned fingers, especially if its one's writing hand. So it's 7 or 8 adjusters per bulb x the adjusters for the matching factor plus the displacement factor for those w/ workman comp injuries. In fact, we may read in the DMA reports about future workman comp abuses related to this issue.
Also agree that the training school adjuster should not be left out. In fact, the training for this sub-set of adjuster skills is quite valuable. Those with this specialized training will be guaranteed to keep busy 365 days a year, even on the 4 key dates of the year. These well-trained adjusters will be highly sought after by the top shelf vendors and carriers. Certain employment agencies will now have ammunition for their claims that they actually do need x more adjusters to fill this new specialty, even in North Dakota.
Finally, we need to account for the indirect demand for the employees associated with the state licensing system. As we know, these are exhaustive agencies in their due diligence as to licensing, and numerous employees are needed to run the printers at the these licensing departments (note these are not investigative positions however). This direct and indirect employment is important in establishing premium pricing for many carriers (given that there are an almost infinite number of staff adjuster positions for newbies). Finally, there must be some indirect employment for database analysis to verify that the costs integrated into the major programs accurately reflect the costs incurred for this zip code. We do not want this to be a mold gold or water sucker bonanza. In fact, I understand that there is a device to test the reliability of the light bulb that will be a required purchase of most adjusters to verify the extent of damage, and a certain engineering company is now developing tests and articles which state the degree to which the light bulb may have been damaged from pre-existing or installation circumstances which may result in subrogation possibilities, but that indirect employment is not to be included in the thought provoking question you posed. Happy holidays everybody :)
