title: What is the initiating actor for the usecase shown here
body: <p>I am new to drawing use case and writing use case descriptions.</p>
  
  <p>I have an Actor called <code>User</code> , an abstract usecase called <code>Work Type</code> and another use case called <code>Manager</code>. The usecase <code>Manager</code> has a generalized relationship with the <code>Work Type</code> use case.</p>
  
  <p>I'm now writing the use case description for <code>Manager</code> use case. And what is the initiating Actor for this use case. Is it the Actor <code>User</code> ? or doesn't it have an initiating Actor ?</p>
  
  <p>Note: I only want to know the initiating Actor for the use case <code>Manager</code></p>
