This study is a pragmatic randomized control trial designed to test the effectiveness of a 12-week, 6-session phone-based coaching intervention to help promote resources and alleviate strain in working adults with chronic illnesses.

Compared with the control group, the coaching group showed significantly improved work ability perceptions, exhaustion burnout, core self-evaluations, and resilience – yet no significant improvements were found for job self-efficacy, disengagement burnout, or job satisfaction
