It's the company's fault? Most often it's the guy pulling the trailer that won't write it up and follow up with the supervisor to make sure it's entered into the computer. Once again back to the old definition of insanity... doing something the same but expecting a different outcome. So after the first guy hurts a shoulder why wasn't it addressed at the local level? The grease gun does not have to be ordered from Ann Arbor, they do have them locally available.
