You are lucky if you do not suffer from any disabilities, but it would be rather arrogant to refuse to acknowledge that many people in the world are differently abled and unfortunately, they are not offered the same opportunities as someone who is perfectly able both mentally and physically. Businesses need to understand this fact and make an active effort to make their businesses more accessible in terms of their employees and their customers.
For customers, accessibility depends on the kind of service that they are providing. For example, If it is a product for everyday use, the labels could be written in bold or bigger fonts to allow readability for people with weaker eyesight. If it is a journalism business with media on the television, then perhaps the news could be laid out in sign language along with the audio to allow people with hearing issues to be able to understand current affairs.
When it comes to your employees, you can make your offices more accessible in different ways. You could add a lift and a ramp to allow wheelchair accessibility. You could assign tasks keeping in mind diversity and being empathetic enough to understand the things that members of a certain group in your staff can or can not do. You could also incorporate standing desks or allow people relaxations based on their needs as an individual and make use of assistive technology in your operations or make using them possible for everyone.
There may be different ways to make your office and your service more accessible and you would have to find creative ways to implement them. You might not be able to implement all the strategies on the internet but if your heart is in the right place, and you want to make a difference, you will be able to do your part in making the world a better place.
