According to wiki:
Effective Mid 2015
In addition, starting mid next year, Citi At Work customers (through relationships Citi has with your employer) will no longer automatically qualify for 'The Citibank Account' via direct deposit. This means you'll be downgraded to Citi Basic Banking at that time and also lose the ability to earn TY Points.
Does anyone have a detailed timeframe when exactly is "Mid 2015"?
