[quote name='Skylander7']Ok.. this came up in a class a long time ago.. and I'm going to really step out on a limb here.
The "at will" laws are usually enacted in benefit of the employer, not employee. Now if you've signed paperwork, I don't know how far you'd get with it.. but it sounds to me like you're experiencing a little workplace harassment (not sexual harassment.. actual harassment). It isn't legal, and it shouldn't float.. especially if your supervisor has been overheard publicly defacing you to your fellow employees.
I encountered a similar situation with my sinus problems. There IS a loophole.. the FMLA (family medical leave act). My boss is the most unprofessional, favoritist, self-absorbed woman on the planet.. and she's been in trouble for workplace harassment before to boot. She was trying to nail me when I had frequent doctor visits leading up to my surgery for my sinuses (headaches, checkups, outpatient services, etc). My company has this FMLA form that you fill out for approval stating that a condition may cause frequent absences.. basically, you're protected after that point. I filed the form, she started harassing me and even demoted me.. one call into HR, and she was in her manager's office. Problem resolved.
If you have been diagnosed with a medical condition, it's a "handicap." Therefore, "at will" law would be null and void via discrimination through the Americans with Disabilities Act of 1990. Get your frequent sinus problems properly diagnosed through an ENT.. file it with HR.. and you're protected.
Like I said.. I'm stepping out on a limb.. but it does sound a little like workplace harassment to me. Now I don't know if Texas has a law similar to Alabama's where you cannot tape a conversation without the other party's consent.. but I would take that tape to someone higher up immediately. Slander in the workplace is not legal, and the manager obviously has no form of formal education in management (or didn't pay attention).
Edit: By the way, this is the Family Medical Leave Act, word for word, from the Dept of Labor's web site.
Synopsis of Law
Covered employers must grant an eligible employee up to a total of 12 workweeks of unpaid leave during any 12-month period for one or more of the following reasons:
* for the birth and care of the newborn child of the employee;
* for placement with the employee of a son or daughter for adoption or foster care;
* to care for an immediate family member (spouse, child, or parent) with a serious health condition; or
* to take medical leave when the employee is unable to work because of a serious health condition.[/QUOTE]
this is what I was thinking about too, but didn't have the details til you brought it up. Good points... Like I said I don't

ing care about this job, but if they try to pin this shit (my absences) then I can simply prove that I have been sick via doctor's reports and case close. I can file a complaint against the principal if she does this shit because she was already in hot water last year with HR and the superintendentsof the school system because she was harassing employees. So no worries.
