When you are about to train a disable person try using a method which can help the employee to understand easily and as fast as he or she can. In the training session, use symbols and hand gesture to explain the entire procedure.
Make sure you explain them solely instead of with others so that they are able to ask any sort of questions if they have ambiguity in their mind related to the given training.
In detail thoroughly explain then the usage of machinery or equipment if there is any involved.
Every office should make sure that they teach other employees the exact manner with the help of which the disabled people can be trained, try making them feel as a part of the office.
The next important thing is to make all sorts of services which are provided in the offices for the employees easily accessible for the disabled employees as well.
Strictly prohibit discrimination and spread the vibes of disability equality in the office.
