Other means by which I got my salary increased were annual merit increment and collective agreement. There was this company I worked that increases salary at confirmation of appointment which was usually a minimum of 5% on basic salary. At the end of annual performance appraisal, salaries were usually increased by between 2.5% - 10%. In the same company which was a Unionized environment, there was usually salary increment based on Collective Agreement between the National Union and the Employers Federation. In effect, in some Unionized companies I worked, my salary was increased by Confirmation of appointment, annual merit and collective agreement increments.
