Improve this with "Tell, don't ask".

function getSalary() : Number
  var employee:Employee = new Employee()
  var salary:Number = employee.salary
  if(employee.hasBonus) {
    salary = employee.salary * 1.1
  }
  return salary
}

Kinda feel as though this function would never exist as is. You would, surely, have the getSalary function as a method of the Employee class?

But..

Class Employee
var salary:Number
var bonus:Number
var hasBonus:Boolean

function getSalary() : Number {
if (hasBonus) {
return salary * bonus
}
return salary
}
End

thus you can then do:

var Ryan:Employee = new Employee()
Ryan.getSalary()

returning the value of the salary without having to break the encapsulation of the employee state - if setBonus has been called then you will get a salary with a bonus, else you wont.
