Post Tax Employee Medical Contributions

[Guest jlcaragianis]

We are considering adding a post tax premuim option to our medical plan for 2010. The purpose would be to allow employees who missed qualifing events etc to enroll or change enrollments. I would be interested in any information on this subject.

One particular question is: if an employee missing adding a new baby to the plan within 30 days, can they drop the pre-tax plan and opt into the post tax plan?
