"...Would even be a great idea for them to finance a franchise for the two to run if theyd like..."
Take some decaf tomorrow.
You open a Starbucks as company-owned, with the two of them as co-managers. You develop an ownership path based on meeting three years of mutually agreed performance statistics in revenue, profit, etc. If they reach it they vest 33% per year for three more years to full ownership.
They could even re-hire the fired boss to work for them and if they write good performance reviews the old boss could get their old position back at another location.
Would be a great ending.
Maybe not for you though. You’d rather just be angry forever.
