READ AND ANSWER - If you do not answer, you will lose your vote and your right to complain.
So we are reaching out to International Confederation of Wizards. As of now Gringotts recognized me as the Minister because I was the last Minister. Until now, there was no reason to do much because it was just us at Hogwarts, but now it's the time to make the decision.
1) Do you want me to stay minister?
2) Do you want to candidate yourself as minister instead?
Once those two very important questions are answered, then we need to discuss Ministry. Like it or not, we will need to form a bureaucracy to deal with that. The roles will need to be much different than before, but we will need a International Magical Department, possibly Obliviators who will need to learn about Muggles in this time. Once we have a full set up, then instead of random assignments you will have full jobs.
Everyone will need to work. No there are no salaries at the moment, but there will be. They will be minor since Hogwarts provides for room and board.
