"This company has went down hill for a whole variety of reasons. There is lack of communication from all levels of management and on top of that, they do not follow their own policies that are written in the handbook. I know this from personal experience and I have been in Security going on 10 plus years at this point. My advice would be to always keep a card or two in your pocket just in case they screw you over like they did me. \n\nIf you are one of their favorites or of a particular demographic then you will be golden but since I am neither, well thats why I left. Even though they did me the way that they did, I still gave a two week notice. So we will see how the next chapter goes."
Both the NOAD and the OED report that ID is an abbreviation for identity, identification. They weren't carrying any ID. I lost my ID card. The term id is used in psychoanalysis, and Id is a variant spelling of Eid. In some contexts, id could be understood as ID, for example in the phrase the user id used when talking of a CMS.
@FumbleFingers - Let me agree that "ID" is short form of "Identity Document". But, we find a commonplace thing, such as, "What is your email ID" or "What is your email id". Obviously, the speaker is asking for "email Identity" or "email Identifier" and not for "email Identity Document" or email Identity Card".
It's actually about whether Id is short for "Identity" or "Identity Document", and therefore it's really about English. But it probably doesn't matter either way in code, since most camel-cased languages idiomatically only capitalise the first letter of acronyms.
