As a person with E, I can truly relate and hate that everyone has to deal with this and go through these experiences which can leave us feeling less than, angry, and not to mention poor! The difficulty in states with at-will employment is that you can be terminated without cause basically. If they are smart, management does not give the employee a reason other than a basic 'sorry, we are no longer in need of your services'. If they actually give you a reason, such as the aforementioned example of excessive use of sick time, THEN you have a potential cause to file a grievance, legal action, etc...the good thing is that a surprising number of employers in at-will states do give folks a reason for termination (which is the right thing to do!). You would have a cause to say, they told me the termination was due to sick, failure to perform, etcc...but it was really because of my E. One important note, before you do anything else, you should file an internal grievance following that companies policy. If it is a larger employer, such as an hospital they will have one. Typically it involves a form and specific process of sending the grievance into personnel. If they do not respond to you, then you can still move forward. I mention this as the very first thing any outside process will ask (such as govt EEOC review board, attorney, etc..) is did you file a grievance with your employer and what was the response? Basically, the concept is a fair one. If the employer (at a higher level such as HR and other administration) did not know of this situation (not the termination but that the reason is to getting rid of you due to E in reality vs whatever the manager is telling them), they, as a company, are much lesss responsible as they had a rouge manager acting on their own outside of company policy blah blah.....even if you know that they all did know, and perhaps even directed this decision, still follow the companies grievance/appeal process or you weaken your case significantly.
for jobs such as nursing...that is a different beast. Make sure that you do not find youself in a role such as surgical nurse, etc....floor nursing in a hospital could be tricky as well...it is easy to justify that there is the potential for a patient to be in some type of danger...now, I know this is mostly ridiculous, as any employee us could suffer a heart attack and have a sliip of a syringe, etc...but, we are stuck with this situation. And, if you do not disclose, well, everyone has spoken to that pretty well. So if you are able, find positions in which you do not have to work with any 'instruments or medical tools'...other than blood pressure cuffs, etc...then you are much safer in terms of employement and probably will make employers much less nervous. An unfortunate reality is that they have a huge liability with patients and get sued on a daily basis...and their insurance companies are looking for an 'out' in any given suit. So....I do NOT agree with the employer, but some untrained managers can have that guide their decisions.
sorry so long, but I support you and was just hoping to provide some info that will give you some ideas about how to manage this....
