I've earned X (the market standard) as a senior software developer when I was healthy. After suffering an RSI-related health issue, I pursued a masters degree in Machine Learning and am on a path to recovery, but currently I can no longer do long hours. Approx. 6 or 7 hours is the max I can work per day, even if there's a deadline.
I'm presenting my RSI-related limited work hours to employers as a short-term or long-term disability. The current market standard pay for senior software developer is X+Y, and for machine learning engineer, it is X+Y+Z. I'm happy if I can at least get paid X, but companies that are willing to recruit me usually pay their normal engineers around 80% of X.
How do employers calculate how much they can pay an employee who has a short-term or long-term disability? Is there any official policy or guide? I'm asking this for jobs in India, but many companies in India have their branches in USA, Germany, Japan or South Korea, so a policy from any of those countries could also be borrowed. If a normal employee is paid X, do they reduce the pay by a certain percentage for a person with disability or do they try to pay the same and yet allow favorable working conditions based on the disability?
