Purpose: The mental health and well-being of employees is negatively impacted by stress, anxiety and depression. There is a need to address these issues at an organisational level to enhance workforce welfare and to decrease the number of days lost due to mental health/well-being concerns. This study aimed to evaluate a mental health and well-being toolkit designed to enhance the resilience, coping and self-talk of employees. Design/methodology/approach: The intervention was derived from counselling psychology and composed of an 8-hour programme, which was delivered over four consecutive weeks. A mixed methods approach was adopted, with the quantitative element assessing an intervention group (n = 10) and control group (n = 14) at baseline and at the end of the programme on measures of mental health and well-being. The qualitative aspect of the study involved interviews with the intervention group, which were thematically analysed.. Findings: Quantitatively, the experimental group showed statistically significant improvements in elements of resilience and well-being and a reduction in stress and anxiety. Qualitatively, participants experienced a positive effect on their well-being, benefited from the learning process, applied the taught strategies widely and found the session experience positive. Research limitations/implications: This was a small pilot study, nevertheless, the mixed methods nature of this investigation indicates that a counselling derived online training programme can enhance the well-being of employees within large organisations. Originality/value: A remotely delivered mental health and well-being toolkit could be a useful resource to enhance the well-being of employees in all organisations.
