Shaping Manager Well‐Being and Functioning in Declining Nonprofit Organizations: The Critical Role of Strategy Implementation

Nonprofit Management and Leadership, EarlyView.
ABSTRACT Under the roof of Christian churches in Central Europe, some nonprofit organizations (NPOs) grow, while others are in marked decline. Our study in this context extends a previous focus on financial indicators to NPO managers' experiences, their role clarity and job satisfaction, during phases of organizational growth and decline. Specifically,
