Hello again and thank you for the information. Although you could potentially pursue a wrongful termination suit under either FMLA or the ADA, the evidence would have to show that the reason you were terminated was not for what the employer perceived as misconduct, but instead because or your, or your father's, medical issues and your request for leave. In other words, the evidence would have to point to the reason for your termination being subterfuge to hide the real reason, the medical leave issues.
That is so even if the reason for your termination seems unfair or arbitrary. Arizona, and NY, for that matter, are both employment "at will" states. That means that an employer may terminate an employee for any, or no, reason and with no notice or warning, unless the reason for the termination is unlawful. The unlawful reasons being discrimination or retaliation for filing for programs like FMLA, WC, OSHA complaints, wage claims or discrimination complaints. Therefore, your termination, even if the timing is poor will not be deemed wrongful unless, as mentioned, the facts show that the medical reasons were why you were terminated (or some other protected class discrimination.)
If you believe that you were let go for the discriminatory reasons I discussed, then you will want to immediately sit down with a local employment law attorney who handles discrimination cases to discuss your next step.
Please feel free to ask for clarification if needed. If none is needed, then if you could take a moment to leave a positive rating in the box above, I will receive credit for assisting you today. Thank you
