Working in the NHS
The staff pledges that are part of the NHS Constitution define what the NHS expects from staff and what staff can expect from NHS employers. One of these pledges is to provide support and opportunities for staff to maintain their health, wellbeing and safety. Further to this, the NHS England Chief Executive announced a major drive to improve the health and wellbeing of health service staff, in a bid to benefit both staff and taxpayers (September 2015).
For more information on the methodology used in the survey (weighted and unweighted scores etc.), please see NHS Staff Survey 2016.
Weighting is applied to scores from the survey as NHS organisations of the same type are likely to have different numbers of employees in each occupational group. This can be for a number of reasons: for example, some organisations issue contracts for services such as catering and cleaning, while other organisations supply them in-house.
These differences can have a significant effect on organisation results, as it is known that different occupational groups tend to answer some questions in different ways. For instance, managers are known to respond more positively than other groups to some questions and an organisation that has a particularly large number of managers may have more positive results simply because of this imbalance. This is why the data is weighted. The weighting procedure described below ensures that no organisation will appear better or worse than others because of any occupational group differences.
