Your employer won't have provided serious illness cover. The Big 3 covered is cancer, heart attack and stroke. While I agree with Michael that income protection is more important, getting a lump sum payment if you get a serious illness can take some financial pressure off.
And like the reason you took out the policy in the first place, the death in service benefit goes with the job. If you leave, the cover goes too. With people leaving jobs all the time, you may be without cover again in the future.
Unless cost is an issue (more likely the critical illness than the life cover), I'd keep the the policies. If one of you died, the other spouse won't complain about being looked after too well. On the other hand, I've had lots of conversations with people who have just claimed on policies for €50,000 to €100,000 and have 3 teenage kids, education costs, lost their husband as well as the income they provided.
