Pros
The few pros would include benefits, cafeteria, volunteer opportunities, and access to an onsite gym.
Cons
I've been working at TIAA for less than a year. It became evident pretty quickly that I made a terrible decision accepting an offer of employment. First of all, I've had four managers in the past 10 months. The turn over and the amount of organizational restructuring is mind boggling. What further blows my mind is that my current manager was fired two years ago and recently brought back. Second, the company recently rescinded its work from home program and started a quiet "strategic" head count reduction. Discontinuing the work from home program not only results in the loss of valuable talent, but it also chips away at what little work life balance there was to begin with. Third, the data is terrible. I was hired to work with data, but what I actually do in-between my secretarial duties is manipulate garbage. You will not find a single source of truth anywhere. Instead we have multiple teams reporting the "same" metric that never matches. Fourth, office politics and passive aggressive behavior run rampant. If someone has an issue with you or your work, you'll find out about it in a group setting via some sort passive aggressive comment or when the bus is backing over you. Don't expect the management team to do anything about it either, they encourage it. And EVERYONE is on some sort of power trip. It's mentally exhausting. Fifth, there is an alarming lack of direction by management.
