Summary:

Currently with our Benefit configuration new hire waiting period is being overridden by another event (Rate Change, Age Change etc.) that occurred during the waiting period.

Content (required):

For example - an Employee hired on Jan 1st, some of the benefits starts from Feb 1st and some April 1st. There is an enrollment window of 1 month. If there is a Rate Change life that occur on March 1 and we process it - it works fine with the benefits starting from Feb 1st but the ones starting from April 1st will now start as of March 1 due to the rate change life event. How to avoid this issue and also make sure all the Benefits plans reflect the new premium.
