Introduction. This article discusses the correlations between social worker’s family resources and their readiness to change. Preliminary definition of the understanding of the analysed categories and the role those categories play in the performance of social work with a family have provided the basis for the analysis of own research results. Material and methods. The diagnostic survey method was used. The Readiness to Change Questionnaire by R. Kriegel and D. Brandt in the Polish adaptation by A. Paszkowska- -Rogacz was used to determine the social workers’ readiness to change in general and in terms of the characteristics that reflect the complexity of the phenomenon. Social worker’s family resources were analysed based on the Conservation of Resources-Evaluation questionnaire, which makes it possible to determine how important the resource is to a respondent, the levels of acquisition and sense of loss of the resource (Dudek, Koniarek, Szymczak, 2007; Hobfoll. 2012). Based on the factor analysis, two sub-scales of family- -related resources were distinguished, which were labelled: Family life balance, and Relations and needs. Results. The results of the study show that the resources related to Family life balance (considering their importance for the respondents as well as their level of acquisition and sense of loss) correlated with individual characteristics of the readiness to change more frequently compared to the resources included in the Relations and needs sub-scale. On the other hand, the level of acquisition of the two analysed factors, i.e., the distinguished sub- -scales of family resources, correlated with the level of the respondents’ general readiness to change. The stronger the sense of the acquisition of resources, the higher the level of the readiness to change. These results show that the process of minimising social workers’ resistance to change in terms of the general level of readiness to change and in terms of five of the seven analysed characteristic can be beneficially influenced not only by a social worker having family resources and the importance thereof but also, albeit to a lesser extent, by the sense of loss felt by the social worker. These results seem important due to the need to strengthen family systems of persons falling into the professional group subjected to the study, as the essence of their profession is to create and facilitate the readiness to change among families in danger of social exclusion or already socially excluded, and to accompany those families in the process.
