Won’t some people take advantage of this process though and ask for unnecessary adjustments where none are needed? Perhaps they might exaggerate a little to get a few extra perks?

It’s possible but I would suggest starting from a position of trust. If your employees have a positive relationship with their manager and the organisation at large, it’s much less likely people will try to take advantage of the system. By law, you have a duty to implement reasonable adjustments if a disabled employee or an individual who lives with a long-term health condition requires them. Be clear and transparent with all your employees about the process of requesting workplace adjustments. Ask your line managers to be proactive in opening up adjustments conversations. Doing this will create a culture where employees feel trusted, valued and heard.
