I've heard of companys making employees sign document stating, that they can be fired for any reason without notice. However does the person who's applying for the job actually have to sign this document?
When I applied at my company 10 years ago I was given a serious of documents to sign. When I came across this document stating I could be fired for any reason without notice I didn't sign it. I was later told the next day when I turned in the paperwork that I had to sign it or I wouldn't get the job. (Actually the way it was said to me was "Do you want to work here?" and when I said yes...I was told "Then sign this or you're not getting the job." Needing this job really bad I decided to sign it.
I started out here as a cashier and after 2 years worked my way up to management and have been doing it every since. One day as I was closing out for the evening the general manager and the owner came in and asked to speak with me before leaving. I went into the general manager office and was told by the owner, that I was being removed from the schedule effective as of that day! I didn't scream or yell or make a scene or anything I simply in a calm way asked "May I ask why I'm being removed from the schedule?" and I was told base on the law the company didn't have to give me a reason to why I was being let go.
They then handed me an envelope with papers to sign and a service package inside stating, that I would receive $510.00 dollars for 6 months every week(This was the amount of my pay per week.) However after reading it the papers included, that by signing and receiving this money I wouldn't go see a lawyer, wouldn't sue the company, or wouldn't go try to collect unemployment and if I did any of this I would have to pay back the money they were giving me. I refuse to sign the document and gave it back to them. I got up...got my things and walked out. Later the next day I received a phone call from the manager stating, that the owner had changed his mind and wanted me to come back to work.
I really needed my job, so I agreed to come back, but only if I was told why I was fired in the first place. The reason the general manager gave me sounded so stupid. You see my friend who once worked for the company is in the military and is off fighting in the war and they said, that I seemed depressed and wasn't concentrating on my work, yet they never asked me if I was depress. I've only been depress one time while working at this company and that's when my grandmother died. They didn't even know I was depress nor did they ask any question to how I felt at the time. I was kind of shocked to hear this reason as to why I was fired. They went on to say that I never spoke to any of the other employees and always kept to myself. Sure I was quite, but it had nothing to do with my friend being in the military. It was because all the employees I worked with were illegal and only speak spanish and it's very hard to talk to them, so I tend to keep to myself and kept myself busy by working.
My question is If I had got a lawyer would this firing me stick on their behalf. I mean do I actually have to talk to the other employees on a personal level in order to keep my job. Sure I try telling them what to do but when it comes to my personal life I tend to keep it out of the work place.

While some companies make employees sign a document acknowledging their status as at-will employees (meaning that they either they or the employer can terminate the employment at any time), the bottom line is that unless there is a bona fide employment contract to the contrary almost all employees are at-will employees.

There is no law that requires employers to give reasons for terminating anyone. There are only laws that say that they cannot terminate employees for illegal reasons (such as on the basis of race, gender, ethnic origin, etc.). It may not be fair, but it's not illegal to not provide a reason for terminating anyone.
