Can an employer keep you from medical care with heart doctor? Can they write you up saying you have no time alotted to go.

An employee normally must abide by the sick leave policy of his employer, unless a city or local ordinance applies.  If the illness or health condition is the result of a workplace injury, the employer cannot terminate an employee for seeking medical attention under the Workers' Compensation Act.  If the medical condition constitutes a disability under the American with Disabilities Act (which is certainly possible with a serious cardiac problem) and the employee has requested a reasonable accommodation with respect to seeking medical care for the disability, the employer cannot terminate the employee for seeking medical care for the disability.If this was just a routine cardiology appointment (and I empathize because I have to see a cardiologist periodically for past incidents which are not disabling to me), the employee normally must use whatever sick leave is available from his employer or must schedule his appointments on his day off.
