From the Teamsters April 7 Prairie Farms update.
We are under a very tight timeline, as the offer made to buy parts of Dean, which has been approved by the Bankruptcy Court, is scheduled to be finalized on April 23. Coincidentally, that date is just before Dean is at risk of running out of money. If the Final Offer isn’t ratified, Prairie Farms could walk away from the deal. This is why this vote is so important.
Looks like you union folks can debate all you want about your CBA until you're blue in the face. I doubt the DOJ will approve this sale by April 30th. They take months to investigate and may not be fully operational due to the virus shutting down non essential government operations.
