A third indeterminacy of labour power: Worker health investment and the indeterminacy of labour health.

Abstract

This article identifies the health of the worker as a third source of labour power indeterminacy to be added to the indeterminacy of labour effort and the indeterminacy of labour mobility. The paper clearly differentiates worker health from effort as a distinct source of labour power indeterminacy-something that cannot be guaranteed and that varies for an individual over time. It considers the relationship between worker health as a new source of indeterminacy and the two extant sources of labour power indeterminacy, focussing on the way in which health moderates the relationship between effort and output. The paper also considers the way in which worker health investment moderates the indeterminacy of labour effort and labour mobility, independently of its impact on the health of the worker. The paper documents the potential value of worker health investment to the organisation and also considers the boundary conditions for investment in worker health.
