The limits for expenditure on personnel that were imposed by the Fiscal Responsibility Act (FRA) have been considered by local health managers as an obstacle to health sector policies. This paper analyzes the linear trend for the personnel expenses indicators and the correlation of this with the profile of spending on health care personnel in 5,356 Brazilian municipalities from 2004 to 2009. The study of the time series used data from the 'Finanças do Brasil' (Finbra) and data from the Information System on Public Health Budgets (SIOPS). There was a trend towards an increase of 1.3% in the annual average of total personnel expenditure in the municipalities, but the cost of health care staff did not follow that growth. There were no correlations between the indicators, and this result is contrary to the arguments given by the health managers. They attribute the problems with hiring workers and the expansion of health systems to the FRA. The availability of data from the Finbra and the Siops system is associated with a lack of knowledge on these issues. This makes it an opportune time for conducting new research.
