When an individual has more than one contract within the same staff group, they are counted once in the headcount but all contracted hours are counted in the FTE number.
Pan fydd gan unigolyn fwy nag un contract o fewn yr un grŵp staff, unwaith y caiff ei gyfrif yn y nifer cyfrif pennau ond caiff yr holl oriau contract eu cyfrif yn y nifer CALl.
