Internet resources and social media are the main reference sources for teachers who resort to various strategies to solve the problems they face. Today, many social networking sites have emerged and have reshaped people's communication, interaction, collaboration, and even the learning process. Teachers make use of the internet and social networks to get the information they produce across in a short period of time to the individuals they want or to use the already produced information to solve the problems they face. This utilization process occurs from time to time in the form of professional solidarity. Teachers' professional solidarity and search for help in social media can be considered to be an important source of insights to be used to determine pre-service and in-service training needs of teachers. Thus, in the current research, problems and help requests channeled by pre-school teachers to their colleagues through social media were examined. This is a qualitative research employing the document analysis method. The data of the study were collected by examining the records of the last five years (2013-2017) in the forum sections subsumed under the heading of interaction-solidarity with colleagues of the site "preschool.com" that the pre-school teachers effectively used. In the current study, as the data collection tool, analysis forms were used. The findings to be obtained in the current study are believed to contribute to the determination of the areas posing threats to the preparation of pre-school teachers for their profession and to their in-service development
