How shift premia expressed in percentage terms, are linked to pay.

There is no set method of doing this. For example, they can be calculated as a percentage of plain time rates; a particular point on an incremental scale; the basic rate for a particular grade (not necessarily that of the individual employee); consolidated rates that include overtime and/or weekend premia; etc. The net result is that although two groups of employees may have the same nominal percentage shift premium, for working an identical pattern of working time, the monetary value of the overall payment they receive can, and frequently does, vary significantly.
