Pros
My specific team is really great. My job is challenging and interesting, and my manager pushes me to learn. It's a pretty collaborative environment on my team.
Cons
I'm relatively new to the organization, but my impression is that leadership is not too diverse and, at least on the legacy Willis side, is made up of a lot of older British white men. I don't see a lot of women or people of color, and, at in some cases Americans seem a little less respected than Brits. This isn't as bad at the middle management level but is clearer in the higher levels of management. Company culture (legacy Willis) is also London-dominated. Meetings can be a little stuffy and overly formal, especially with overseas colleagues, but also in the US. The dress code in some offices seems very formal for employees who aren't meeting clients that day. IT and HR systems seem poor. Legacy Willis has a strange performance review system where people get anonymous feedback from coworkers which seems secretive and like it would foster a culture of saying things behind people's back. Benefits are poor compared to other companies where I have worked (401k especially). There is not the same sense of feeling like upper management has your best interest in mind as I've felt at other companies. There is not a collective feeling of "we're in this together" - instead, it feels more like senior management is just working for themselves. Making a buck is definitely valued higher than looking out for employees. Of course profit is important, but at other companies I've worked at, profit and doing good work and being a team all seemed linked together, rather than it being a trade off. It also still feels like two distinct companies as Towers Watson and Willis have separate offices even in the same cities and don't interact much - this makes sense given that the companies specialized in different things, but working in the same building as people from Towers Watson would make me feel more like it was one company, and I'd have the chance to get to know those people. Working from home is somewhat discouraged in some departments, which seems outdated and unnecessary. Also sometimes there is an unspoken pressure to stay late in the office, when it'd be preferable to leave earlier but just log on from home later instead. Or with long commutes, sometimes it'd just be more efficient to work from home now and then.
