title: Salesforce Field-Level Security for User Object
body: <p>I have a custom field in the Salesforce User object.  I am trying to work out permissions. I only want the User's manager and System Admins to be able to see this field.</p>
  
  <p>Looking at the field-level security options, I see:  Contract Manager.  I worry that if I check this, ALL contract managers will be able to see this field.  Is that the case?</p>
  
  <p>Is there an easy way to accomplish this security policy and test it in a sandbox where I am not allowed to have many users?</p>
