Re: Can your employer find out your health records?
That I am not sure of but I would think no. Employers rarely look at records unless it's a small company that handles their own insurance processing.
The biggiest thing for you it seems is that you may be worried about either loosing or not getting a job due to an illness. Honestly I wouldn't be so worried.
Lets say hypothetically you got a new job but previously you were being treated for depression and your current company found out about it (or even if it is at a job you had a long time) they can not by law fire you. It is illegal and discrimination.
If you are doing your job without problems they can't do anything. However, some companies are just rotten and they will fire at will and do not have to give you a valid reason or make one up and you can't prove they fired you for a health reason. And if thats the type of company you work for then you are better of with a new job.
On the other hand, if someone has a criminal record and fails to disclose that information then it is legal to fire them, particularly if its a job in retail and that person has charges for theft.
Definately do some research, try google, to see what your state laws are. My husband went through a similiar thing where he has depression and didnt want the company to find out so he paid cash for his visits before we got married. It took me a while to convince him that it was better to let them be aware of it because when he needed time off he was able to get FMLA and short term disability. I went through a similiar thing were I didn't tell the company I worked for that I was in fact handicapped, it didn't prevent me from doing my job, I just didn't think they needed to know until I had to be placed in a wheelchair.
