It’s on top but in lieu of the 99 weeks so if someone is at 98 weeks then they can apply for the additional 73 weeks. What you say is correct if one hasn’t already applied for their Federal Extension then it will be 73 and not 99 weeks. Now if the benefits have already been exhausted past the 99 weeks and that person still has not found a job then they can file for an “Emergency Federal Unemployment Benefits Extension”. The Unemployment Office will interview the person and make sure they have been actively still searching and based on the answer will give a yes or no. If approved, they will deduct the number of weeks it has been expired from the current 73 weeks
Please cite a link for that claim. I ask because that is not stated in the article.
