Medical coverage during my employment was decent coverage for my needs.
Health Insurance is a bit pricey
Great benefits package for full time employees
They had reasonably priced health benefits. The thing I did not like about their benefits is that you had to earn you PTO instead of already have it when hired.
All core benefits are offered through the company and for medical you have various options for plans and providers
Great benefits - new paternity leave policy is generous! good 401k plan and lots of voluntary options
401K contribution by Mercer is excellent.
Like all companies it keeps changing
Reasonable amount of sick/vacation time provided, along with paid Holidays (including some paid half days before/after major Holidays). Pension was recently discontinued, but Mercer replaced with an increased Employer match to 401k. Multiple Health Insurance options so you can choose what meets your needs best.
Rate of compensation was as good as any other. However, they demanded you ear every penny of it. Medical benefits was good as was their employee investment plan that is unusual in this current market.
