how tight should types be?
You want to do some sort of type narrowing so you can be certain that the properties exist. Here's the TS docs on that. https://www.typescriptlang.org/docs/handbook/2/narrowing.html One option is to create a common property on all these types in the union and check that value like this: 
type Tasker = 
  {
    _id: ObjectId;
    name: string;
    email: string;
    kind: "someIdentifier"
  }
| {
    email: string;
    kind: "anotherIdentifier";
  }
| {
    persona: string;
    kind: "yetAnother";
  };
type Tasker = 
  {
    _id: ObjectId;
    name: string;
    email: string;
    kind: "someIdentifier"
  }
| {
    email: string;
    kind: "anotherIdentifier";
  }
| {
    persona: string;
    kind: "yetAnother";
  };
function getTaskerName(tasker: Tasker) {
  if (tasker.kind === "someIdentifier") return tasker.name
}
function getTaskerName(tasker: Tasker) {
  if (tasker.kind === "someIdentifier") return tasker.name
}
