This article studies the influence of national context and collective bargaining on the factors taken into account when adjusting wages. Using data from Spanish and British manufacturing establishments, we examine the relative importance of the cost of living, the ability to recruit or retain employees, the financial performance of the organisation and the industrial relations climate on wage adjustments of manual workers at the establishment level. Our findings show that there are significant differences on the importance given to these factors in both countries. In part, these are related to differences in the incidence of collective bargaining.
