Is this even legal?

My job laid everyone but me off and told me I have to work a minimum of 55 hours a week moved me from hourly to salery and said when my bosses are there i have to be there 7 days a week sometimes up to 1 am at night. He told me to bring my dog to work, not make any plans with my friends and basically live out of the work place, just go home and sleep. Not to mention no benefits or 401k I was making 13/hr before which before taxes was 2080 a month and after taxes came to about 1580 a month, and now he is going to give me 2000 a month no taxes taken out but put me on 1099 and have me pay the taxes at the end of the year so in a way its apay cut. Is this even legal, and its basically like I do this or i have no job. Of course I am looking for another job now ASAP but i cant leave here since I have rent and bills that need to be paid. I am so upset :(
