salary is the monitory benift for the managerial grade and 
issued on a monthly basis(mostly). this does not indicate 
the number of hours worked in specific. those employees who 
are in the payroll of the company are entitled for salary.

wages are monitory and applicable for the labour workforce. 
this purely is based on the number of days worked, hours of 
work, quantity of workload, etc.... these employees may not 
be in the payroll.....may be partime employees, contracts 
etc.....
