ny law regarding telecommuting

Under certain circumstances, an employer may be required to make certain reasonable accomodations if you have a temporary disability, although I don't know if telecommuting would be considered one.  However, absent something like that, or an employment contract or employee handbook which provides that employees can telecommute, your employer does not have to agree to your request to change the conditions of your employment, and can demand consideration (such as your agreement to change your employment status) in return.
