One "ism" that may commonly affect early childhood professionals is classism. Classism refers to "an attitude, action, or practice of an individual or institution, backed by societal power, that gives preferential treatment to or treats as superior those with more economic resources or higher social status and treats as inferior or denies access to those with fewer economic resources or less social status" (Derman-Sparks & Olsen Edwards, 2010, p. xi). Majority of early childhood professionals are payed poorly and do not receive benefits which often leads to more frequent staffing changes. "The economic status of many early childhood teachers may also result in tensions with some of the families in the program who are more affluent then the teachers" (Derman-Sparks & Olsen Edwards, 2010, p. 110). Some parents may not respect the teacher's opinions or value the work they do because it is a lower paying job. I have heard many teachers complain that some people just view them as "babysitters" and do not understand the true value in what the teachers are doing on a daily basis.
If teachers are experiencing classism in there personal lives or in the workplace it could interfere with forming positive relationships with all the parents and families they work with. They may be less likely to invite some of the families into the classroom or less likely to speak freely and start conversations with some of the parents. On the other hand, in the classroom the teacher may be more conscious of ensuring that all the children are treated fairly and respectfully. The teacher may be able to help children learn how to stand up for themselves and appreciate differences in others better than if they never experienced an bias behaviors. When experiencing a personal "ism" teachers are more aware of the pre-biases that may be forming and might be more motivated to try to stop them from forming in the children they work with.
