What if my employer continue to pressure me to go against my doctor's medical order?

Your employer is not required to follow your doctor's medical orders except under two circumstances. First, if you have a serious health condition and are eligible for coverage by the Family and Medical Leave Act (FMLA). The FMLA provides covered employees who work for covered employers with up to 12 weeks of leave for a serious health condition.  Not all employers and not all employees are covered by FMLA.  The serious health condition can be the employee's own or of an immediate family member. If an employee on FMLA is able to return to work in 12 weeks or less, then the employer must return the employee to the same or equivalent position.  Employees are also allow to take FMLA on a intermittent basis (here and there as needed).FMLA makes it unlawful for a covered employer to interfere with an employee's FMLA rights or leave or retaliate against an employee for exercising FMLA rights.  Second, if you have a disability, your employer may have to accommodate that disability under the Americans With Disabilities Act (ADA). The ADA prohibits discrimination against employees or applicants for employment due to a disability.  The ADA also requires an employer to provide a reasonable accommodation to an employee or applicant with a disability that will allow the person to perform the essential functions of the job.    Employers are allowed to change the nature of any job at any time as your employer did. However, if you are covered by the ADA, your employer will have to provide you with a reasonable accommodation if there is a reasonable accommodation available.  In general, simply excusing you from completing a large portion of your job duties (4 hours of work per day) will not be reasonable.  Even so, there may be other accommodations the employer can make.
