You have an employment contract? Check the contract to see if it addresses this issue. If not, the general rule is that the prospective employer does not have to give the results. But if the employer is rescinding a contract on this basis, it is in the employer's interests to say so, so there may be some breakdown in communications here.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
Ms. McCall is correct. The employer is not required to reveal the blood test results to you. Remember that unless you have a term contract, or one that can be terminated for some kind of cause, you are an at will employee, meaning the employer can terminate you for any reason, or even no reason. The employer has no duty to justify its decision to let you go, so it has no duty to show you the test result.
That said, I would not assume you have not been hired. If you were told to start Monday, be there Monday ready to start.
Good luck to you.
