My employer changed my position because of a medicications for epilepsy,I travel all the time and never see my family I am paid hourly,hotels,and meals that sometime take months to be reimbursed I barely make 29grand a year but for never seeing my family should I not be making more money?

NO? You make as much as they offer and you accept.

I also will note, they should be paying your hotel and meals back within one pay period. So you need to demand your money for those. * or be given a company credit card to use in travel.

I will have to ask where you are at < US or other nation)
I know that if you have epilepsy you have a very hard time getting a drivers license, in fact you can't in most places. So I will assume all travel is by plane, and taxi ?
