DAmn! That is crazy! Tossin' out perfectly good tools!
Check the “hoarding” threads on GJ.
Companies toss stuff because it costs more to sort or repair stuff than it is worth to pay the people who work there to fix the stuff, or maybe than the storage space is worth.
I would presume either a new granite plate was needed in a larger size, or that one had become out of spec for some reason, do into the dumpster it went.
The same possibly for the depth gages.
Once the items are thrown in the dumpster, they are legally disposed of, and can be written off of taxes as no longer in inventory, and therefore no longer a “stored asset” on the companies books.
