Oracle SQL output wrong

I am not being able to produce the desired results of this question:

Display alphabetically the full name, job, salary, department number for each employee who earns less than the best paid unionized employee

• unionized employees are not managers presidents of vice presidents And do not work in SALES or MARKETING departments
• Full name should be displayed as Firstname Lastname and should have the heading Employee.
• Salary should be left-padded with the = symbol till the width of 12 characters. It should have an alias Salary.
• salary is formatted as a currency amount incl. thousand separator, but no decimals
• Limit the width of the Employees name to 25 characters.

The output lines should look like this sample line:

Jonathon Taylor     SA_REP  ==== $8,600     80 

My query so far:

select last_name || ', ' || first_name "full name", job_id, salary, department_id
from employees   
where salary < ANY
          (SELECT MAX(salary)
          from employees e join departments d
          where e.job_id <> 'AC_MGR' OR 'AD_VP' OR 'AD_PRES'
          AND d.department_name <> 'SALES' OR 'MARKETING'
          GROUP BY department_id)

If someone can help me out and point me in the right direction of how to get the proper output, that would be greatly appreciated. Thank you!
