Filer, email quota hog
For work I have folders, sub-folders, sub-sub-folders, etc.. I keep everything. Having worked in several Fortune 50 firms (the financial firms being the worst) and surrounded by clueless idiots I have no choice. I keep getting notices about my email going over my quota, I keep ignoring them. I don't have to delete anything thanks to Sarbanes-Oxley. Sorry servers admins. Besides, it's not my fault clueless idiots keep sending me Word documents chock full of bloated graphics and their endless stream of constant subsequent revisions.
You might suggest, "Just keep the latest revision." Ahh but this is corporate IT and this environment does not allow for simple solutions.
"Why is this project taking so long?"
"Well the constant changes to the original plan kept changing the scope."
"You were copied on all correspondence, check your email."
"Umm, I can't find them right now, I have so many emails, could you re-forward them along with the bloated attachments?"
"Give me a few minutes and you'll have them."
This scenario happens regularly throughout the course of the day. In all fairness we all are juggling more projects than we can handle so I don't blame them for amnesia, happens to me too. Another reason why I keep everything. Those emails I just forwarded? Yea, I'm keeping them too along with their bloated attachments as proof this conversation happened. Oops, another email quota notification. Ignore.
In an environment where when something goes wrong the first priority is placing blame email is your CYA armor.
