My question involves labor and employment law for the state of: Texas

In February 2014, I was laid off with around 60 other employees. The reason given was "budget-related", and I was classified as eligible for rehire. I am 54 years old.

Earlier this month, I saw that my former employer was advertising my former job. The description and requirements describe my former job practically verbatim to my original job description. Since I was classified as eligible for rehire when laid off, I applied for the job, but have heard absolutely nothing at all. During my time at this employer, I was never reprimanded or "written up", and my performance appraisal rated me as above average.

Two people have told me that if I am not interviewed for this job, this is considered age discrimination. These people are NOT lawyers, but they manage companies and hire/fire people.

I have gone through EEOC.gov for a while but can't find any information pertaining to my situation. Can anyone comment? Being in Texas, I can't see any legal reason why my former employer is required to consider me for rehire.
