The 2024 Index shows that 16pc of employees are addicted to or have an unhealthy relationship with Class A or illicit drugs.
Overall, two in five Irish workers report addiction to or an unhealthy relationship with at least one substance, nicotine (29pc) and alcohol (21pc) being the most prevalent.
The data shows that men, those aged 24 and under, and those with a disability or health condition are more likely to struggle with addiction. And senior managers are also more likely to report unhealthy relationships with substances compared to those in more junior roles.
There is a growing prevalence of other addictions impacting the workplace with almost a third of workers saying they have an unhealthy relationship with social media.
Some 30pc have the same problem with work itself.
One in five respondents identify similar struggles with pornography or sex, mirroring the figure of 19pc for gambling addiction.
Sinéad Proos, head of health and wellbeing at Laya Healthcare said: “Employers should recognise addiction as a serious issue impacting Irish workplaces, encompassing substance use, gambling, and social media.
“While these results are concerning, they also present a valuable opportunity for employers to prioritise employee wellbeing.
“By fostering a supportive culture and providing access to resources like counselling and employee assistance programs, we can support and empower employees to make the first steps towards improving their health and wellbeing.”
One in two employees report living with an underlying health condition or mental wellbeing issue. Anxiety and depression are the most commonly cited conditions, with one in ten Irish employees having a diagnosis of depression.
Some 54pc of f those with a health condition or disability admit they would be embarrassed to speak to their employer about it, while one in two with a mental health condition fear being treated differently if they disclose it to their employer.
Ms Proos said: “Employers and employees need to communicate more openly about health conditions and disabilities. Not having a diagnosis or feeling unable to discuss needed support can cause unnecessary stress and hardship for team members.
“It’s crucial that organisations prioritise clear communication about health and wellbeing resources, making them easily accessible so employees can get the support they deserve.”
