So true. I've worked at the same company for 18 years. I've seen lots of people move on or retire. Literally within days they are wholly forgotten or at least never mentioned again. I've never seen anyone that is not easily replaced. It has drilled into me over and over again that we are all just cogs in the machine. Even someone who has been at the company for 30 years and is celebrated when they retire is totally not missed and forgotten within days of their leaving.
