Java Inheritance - cannot find Symbol Constructor

I can't figure out how to compile my subclass even though it calls the superclasses constructor?

This is the class that won't compile:

package departments;
import employees.*;

public class DepartmentEmployee extends Employee{

    private Department department;

    public DepartmentEmployee(Profile profile, Address address, Occupation occupation,   Department department) {
        assert (department != null) : "invalid Department";
        super(profile, address, occupation);
        this.department = department;
    }

}

This is the superclass:

package employees;

public class Employee {

    protected Profile profile;
    protected Address address;
    protected Occupation occupation;

    protected Employee(Profile profile, Address address, Occupation occupation) {
        assert (profile != null) : "invalid Profile";
        assert (address != null) : "invalid Address";
        assert (occupation != null) : "invalid Occupation";
        this.profile = profile;
        this.address = address;
        this.occupation = occupation;
    }

}

The subclass keeps on saying "cannot find symbol - constructor Employee". The two are in different packages. Did I link them correctly?

The super() needs to be the first call in the constructor. Rearrange it above the assert.

Invocation of a superclass constructor must be the first line in the subclass constructor.
