This article examines one aspect of the criticism of inauthenticity that can be levelled against the trustworthiness of professional relationships in general and nurse-patient relationships in particular. The overall question is: are such relationships inherently trustworthy or untrustworthy, from the patient’s point of view? The author concludes that, in spite of legitimate grounds for concern, and while it remains true that nurse-patient relationships may be untrustworthy, they are not inherently so for reasons of inauthenticity relating to emotional labour. The arguments (...) used to defend this claim take their force from the idea that different criteria may be needed to assess the authenticity of nurse-patient relationships from those used to evaluate authenticity in ordinary social relationships. The utility of Hochschild’s idea of ‘deep’ acting, as offering a useful model for the management of emotions in nursing, is examined and rejected. (shrink)
