Update member forumla to exclude employees hired after a specific date

Summary:

Content (please ensure you mask any confidential information):

I need to update the member formula for our bonus calculation in Workforce. The goal is to exclude anyone hired after September 1st from receiving a bonus.
I believe using `CalcStartDate` is the best approach for this, but I'm unsure of the specific formula or method to implement this correctly. Could you please advise on the best way to achieve this?
