Aim
To explore factors associated with non‐disclosure of Type 2 diabetes to employers among Danish workers with Type 2 diabetes.

Methods
A total of 705 workers with Type 2 diabetes completed a Danish cross‐sectional survey. Logistic regression models were used to estimate the associations between background characteristics and probability of non‐disclosure of diabetes to the employer. The models were mutually adjusted for background characteristics, socioeconomic‐, diabetes‐ and work‐related factors.

Results
Among the participants, 23% had not disclosed their Type 2 diabetes to their current employer. Non‐disclosure was associated with more sickness absence, more years with diabetes, greater use of diabetic medication, higher educational level and a perception of not being respected by superior. Personal traits such as gender, age and well‐being were not associated with disclosure.

Conclusions
Among the feasible targets for interventions, good psychosocial work environment was associated with disclosure.
