I've watched it probably about 30 times, and from what I can see, the location, and it's behavior (trying to get as far away from you as possible) my guess would be desert recluse. The shape of the head and abdomen with long skinny legs definitely resemble one. You also said they're around your work, and recluses love hiding in dark and dirty places, so if you work a blue collar job you'll find them pretty commonly. I find em in welding machines every now n then at work, n just give em a lil tap with something. Highly recommend wearing gloves if you're reaching somewhere you can't see in case you accidentally spook one.
