Notes:
The number of years service in the NHS of an EMPLOYEE, it is calculated by summing the number of years of each period of NHS service.

Each period of NHS service is established by the calculating the number of years from the EMPLOYMENT HISTORY NHS JOINING DATE of a recorded EMPLOYMENT HISTORY to the next EMPLOYMENT HISTORY NHS LEAVING DATE of a recorded EMPLOYMENT HISTORY.

This should start with the first recorded EMPLOYMENT HISTORY NHS JOINING DATE and end either with the last recorded EMPLOYMENT HISTORY NHS LEAVING DATE where the EMPLOYEE has not subsequently re-joined the NHS

or

the REPORTING PERIOD END DATE where the EMPLOYEE is currently employed in the NHS and will therefore not have a recorded EMPLOYMENT HISTORY NHS LEAVING DATE for the current employment in the NHS.
