Boolean naming convention
I would use simply HasEmployees.

In case of Boolean, I always try to use hasSomething or isSomething. In Java, many libraries use this strategy (it's just a convention). And I like it, because it's so easy to read when you see:

if(annoyingEmployee.isRemovable() &amp;&amp; !annoyingEmployee.hasBirthday()) {
  manager.fireEmployee(annoyingEmployee);
}
