Disabled people and those with long-term health problems are more likely to experience discrimination, it has been suggested.
According to a study conducted by the Equality and Human Rights Commission (EHRC), such employees reported more negative experiences in the office.
For example, 25 per cent of those questioned reported that someone was continually checking up on them and their work when it was not necessary.
This compares to 19.4 per cent of workers without long-term ill-health or a disability.
Meanwhile, 11.6 per cent of disabled workers claimed to have experienced physical violence at work, compared to 5.5 per cent of other employees.
"If disabled people and those with long-term ill-health are more likely to experience hostile and negative treatment at work, we risk losing both their talent and their economic contribution," stated Nicola Brewer, chief executive of the EHRC.
Established under the Equality Act 2006, the EHRC is a non-departmental public body that is independent of the government.
