Selecting from more than one model in an eloquent many to many relationship

I have a many-to-many relationship in my app between

, and I am trying to determine how to query for all "Employees" who work for a set of companies.

For example I may wish to select all the employees of "Industry Corp" and "Shovels Unlimited"

Example Data Relation

If I query for these individually I will get [Sam, Nathan] for Industry Corp, and [Kory, Nathan] for Shovels Unlimited

[Sam, Nathan, Kory, Nathan]

But I cannot simply

Yeah, you want to use whereHas.

$employer_ids = [1, 2, 3];  // These are ids of employers you want to get all employees for.
$employees = Employee::whereHas('employers', function($q) use ($employer_ids) {
    $q->whereIn('employer_id', $employer_ids);
