NVS can terminate you by eliminating your position; but if the EEOC got involved, they would have the burden of proof to show that you would have been terminated regardless of your status at the time the terminations take place.
Being out under FMLA or STDL only increases the risk that NVS takes in terminating you. This is obviously a company willing to take on significant risk, so good luck!
If you really think there is a problem, take a look at the following links:

Here is an excerpt from their website:
The U.S. Equal Employment Opportunity Commission (EEOC) is responsible for enforcing federal laws that make it illegal to discriminate against a job applicant or an employee because of the person's race, color, religion, sex (including pregnancy), national origin, age (40 or older), disability or genetic information. It is also illegal to discriminate against a person because the person complained about discrimination, filed a charge of discrimination, or participated in an employment discrimination investigation or lawsuit.
Most employers with at least 15 employees are covered by EEOC laws (20 employees in age discrimination cases). Most labor unions and employment agencies are also covered.
The laws apply to all types of work situations, including hiring, firing, promotions, harassment, training, wages, and benefits.
Authority & Role
The EEOC has the authority to investigate charges of discrimination against employers who are covered by the law. Our role in an investigation is to fairly and accurately assess the allegations in the charge and then make a finding. If we find that discrimination has occurred, we will try to settle the charge. If we aren't successful, we have the authority to file a lawsuit to protect the rights of individuals and the interests of the public. We do not, however, file lawsuits in all cases where we find discrimination.
If the EEOC finds there may be wrongful termination involded in your termination; they will sue NVS on behalf of you without charging you a dime!
