Someone on here several weeks ago claimed that if you went into Global Directory, you could tell that someone had been laid off if you looked at their email address and it said, "@iuo.citi.com" instead of just "@citi.com".
Today, I noticed that someone on my team (same region) whom I am 100% positive has been put on notice does not have IUO in her email address and yet I do, but i have not been put on notice.
