The very same employees that were being overseen by the FDA when they were working for Monsanto, leaving Monsanto to work for the FDA to oversee Monsanto. Some not only switch jobs from Monsanto to the FDA, but later on go back to work for Monsanto. That kind of job change does not happen in the general public. When the typical person switch jobs it is usually in the same or similar position that they had in the previous company. In most case the person might be working for a company that competes with the one they left.
