Pros
I absolutely love working at Mercer. My line manager is honestly the most emphathetic person I've ever worked with - I always feel valued and supported. The company itself, from the top down, has a great perspective on diversity, equity and inclusion. From the gender neutral toilets (as well as male and female toilets) to the policies and practices that leadership put in place, e.g. 16 weeks paternity full pay! It was only 2 weeks paternity pay at my previous company. Mercer doesn't just 'talk the talk', it puts its beliefs into actual action which is demonstrated in its policies and the way that line management are trained. Aside from that, the company is also innovative and successful in generating new revenue streams. For such a large organisation, it moves quickly. In terms of benefits, the pay is good, the additional benefits like year-end bonus, ISAs at a discounted price, the MMC shares scheme, the private healthcare and the pension are all really great! There's a whole host of other benefits as well - too many to list!
Cons
The only con I can think of is that the technology is a little behind the times. But Mercer are currently working to improve that.
