• horizontal skills, which involve a broadening of skills in terms of the range of tasks
• vertical skills, which involve acquiring skills of a higher level
• depth skills, which involve a high level of skills in specialised areas relating to the same job.
Skill-based pay differs in the following respects from traditional pay systems which reflect skills differences in a structure consisting of rates of pay for unskilled, semi-skilled and skilled workers:
• Skill-based pay is a person-based and not a job-based, system. It rewards a person for what he/she, rather than the job, is worth. Job worth is reflected in a basic rate of pay for minimum skills, but pay progression is directly linked to skills acquisition (rather than to general pay increases applicable to all) .
• It rewards (and therefore emphasizes) a broad range of skills which makes the employee multi-skilled and therefore flexible.
• It positively encourages skills development.
• A skill-based pay system may not necessarily reflect how well the skill is used, as this falls within the performance component of pay. But there is nothing to prevent injecting performance criteria into the system. In such cases the system will be more performanceoriented than a structure which merely recognizes different rates of pay for
