Based on role accumulation theory (Goode, 1960), this study examines the possibility that there may be additional positive outcomes to employees who sometimes feel obligated or pressured to engage in OCB.
Work-family literature has yielded two competing viewpoints: (1) work-family conflict, drawn from role strain theory and (2) work-family enrichment, drawn from role accumulation theory.
Role accumulation theory was introduced as a challenge to the assumption that multiple roles result in role strain Despite empirical investigations that support the assumption that role conflict and role overload from multiple roles lead to role strain, millions of individuals continue to occupy multiple roles successfully.
2002) empirically examined multiple roles of managerial women based on role accumulation theory and found that multiple roles provide life satisfaction, self-esteem, and self-acceptance; furthermore, a qualitative review revealed that multiple roles of managerial women provide psychological benefits, emotional advice and support, practice at multitasking, opportunities to enrich interpersonal skills, and leadership skills.
Drawing on role accumulation theory and Kahn's (1990) conceptualization of job engagement, when individuals feel pressured to perform above and beyond their job description, the added pressure is likely to produce a sense of heightened awareness and attention to one's work, enabling active participation and a display of increased emotional and physical energy.

Credit for the first attempt to knot these two strands of thought into an elaborated version of Marxian accumulation theory goes to Michal Kalecki, whose published works in Polish in the early 1930s articulated, according to Joan Robinson and others, the main tenets of the contemporaneous Keynesian revolution in the West.
Under the mutation accumulation theory, this result is obvious, because the equilibrium frequency of deleterious mutations will be lower when the selection pressure against them is stronger.
Under the mutation accumulation theory, we are interested in gene frequency change per generation.
This means that under the mutation accumulation theory with equal density dependence in fertilities, greater extrinsic mortality implies more rapid senescence.
