title: 2 relationships between 2 entities in ER diagram
body: <p>I'm trying to draw an ER diagram describing the following:</p>
  
  <p>-"Department" employs "Employees"</p>
  
  <p>-Some "Employees" are "Special" and have more attributes</p>
  
  <p>-Some of the "Employees" ("Special" and non special) are "Managers"</p>
  
  <p>-"Managers" manage "Departments"</p>
  
  <p>So, to convey this I have:</p>
  
  <pre><code>Department ------(employs)------- Employee-----&lt;--------Special
        |                             |
        |-----------(manages)----------
  </code></pre>
  
  <p>From my understanding, I cannot have 2 relationships between 2 entities. How do I deal with this situation then?</p>
