Some disabilities in the workplace can be cancer, sleep disorders, arthritis, bipolar disorder, or even hearing loss because of old age. Even though some conditions are more severe than others, all of them can affect someone in their workplace. For example, a worker that has cancer can fall behind on work, be distracted, or miss work because of this disease. All of those things can result in the cancer patient being fired or loosing respect in their workplace, if people don’t know.  For a disease most people don’t want, that’s a big price to pay. But, if they disclose their medical information to their employer they would receive accommodations (being able to skip for a doctors appointment), have an open relationship with their employer, and regain job security.

Disabilities found in a workplace not only affect the person with the disability but also the workplace that they are involved in. They should have a spot in the workforce because just like people without disabilities they have equal rights and deserve everything the other employees have. Disabled persons add a new perspective or diversity to a workplace because of how they simply handle work and finish the requirements of the job. A lot of people are closed-minded when it comes to what they think is acceptable in our society. Once they accept someone who is disabled, this helps them accept other ways of working and thinking about their job. Lastly, making a workplace more diverse lets the community know which workplaces are progressive with new ideas.
