Question

XYZ holdings have many branches. Each branch has a name and is located in a different province.
Each branch has several departments such as marketing, finance, sales and customer relations.
For a department to exist there must be employees employed in each of the departments.
An employee is ether a permanent staff member or a temporary staff member. The difference
between these two types of employees exist in the facts that permanent staff earns a fixed salary
of R30 000 every month and has a medical aid benefit whereas temporary staff members has an
hourly rate of R400 per hour and their monthly salary is dependent on the number of hours
worked each month multiplied by their hourly rate. Temporary staff members also do not have a
medical aid benefit. All employees, however, have a name, surname and employee number.
