The authors examined the effects of the type of mentoring relationship and the gender composition of the relationship on mentoring functions and career outcomes reported by 352 female and 257 male protégés. Protégés of informal mentors viewed their mentors as more effective and received greater compensation than protégés of formal mentors. Protégés with informal mentors also received more career outcomes than nonmentored individuals, but no significant differences were found between nonmentored and formally mentored individuals. The gender composition of the relationship affected mentoring functions and outcomes, and protégé gender interacted with the type of relationship to affect mentoring functions.

This article broadens our perspective of stigma by examining the process of disclosing an invisible stigmatized identity in work and nonwork domains. I present a model that examines the effects of individual and environmental factors on disclosure decisions across life domains. Individuals may disclose their stigma to varying degrees across life domains, and this inconsistency leads to disclosure disconnects. I examine psychological states and outcomes associated with disclosure disconnects and offer directions for future research.I am grateful for helpful comments and feedback from the editor and anonymous reviewers.This section lays the foundation for the article by defining stigma, by describing how individuals manage their invisible stigmatized identity in work and nonwork domains, and by distin- 2008 195 Ragins

A model of perceived sexual orientation discrimination was tested in a national sample of 534 gay and lesbian employees. The effects of legislation, organizational policies and practices, and work group composition on perceived sexual orientation discrimination were examined, as well as the attitudinal and organizational outcomes associated with discrimination. Gay employees were more likely to report discrimination when employed in groups that were primarily heterosexual and in organizations that lacked supportive policies and were not covered by protective legislation. Disclosure of sexual orientation at work was related to discrimination and antecedent variables. Perceived discrimination was associated with negative work attitudes and fewer promotions. Organizational policies and practices had the strongest impact on perceived discrimination and were directly related to outcomes.

Stigma theory was used to examine the fears underlying the disclosure of a gay identity at work. Using a national sample of 534 gay, lesbian, and bisexual employees, this study examined the antecedents that affect the degree of disclosure of a gay identity at work and, for those who had not disclosed, the factors that influence their fears about full disclosure. Employees reported less fear and more disclosure when they worked in a group that was perceived as supportive and sharing their stigma. Perceptions of past experience with sexual orientation discrimination were related to increased fears but to greater disclosure. For those who had not fully disclosed their stigma, the fears associated with disclosure predicted job attitudes, psychological strain, work environment, and career outcomes. However, actual disclosure was unrelated to these variables. The utility of fear of disclosure for understanding processes underlying the disclosure of gay and other invisible stigmatized identities in the workplace is discussed.

Employing a national sample of 1,162 employees, we examined the relationship between joh and career attitudes and the presence of a mentor, the mentor's type (formal or informal), the quality ofthe mentoring relationship, and the perceived effectiveness and design of a formal mentoring program. Satisfaction with a mentoring relationship had a stronger impact on attitudes than the presence of a mentor, whether the relationship was formal or informal, or the design of a formal mentoring program.
