How long do i have to wait to close my 401k account when laid off indefinately?

I was laid off for lack of work. I was told my insurance would be cancelled Jan. 1 (6 weeks) I then asked if it was permanent and was told "I don't know what the future holds, I'm Soooo sorry. I was then escorted to my toolbox by the president of the company and told to clean out my tools. She stood there and kept both eyes glued to me to make sure I didn't steal anything. She then told my supervisor to escort me to my car. This was a company I had been with and loyal to for 4 years. Now I was being treated like a criminal. I got a strong message that I was not going to be called back. I have about $800 in a 401k. When I tried to get the money out I was told I couldn't touch it because I was not terminated. I called my H.R. and she said "We may still call you back". I was told by A.B.G that there is no time limit for them to decide whether it is permanant or not. How can this be? There must be a legal cut off point, or they could say this for the rest of my life: "We may call you back someday" I have a 9 year old son who is losing his health insurance in 2 weeks and now won't have much of a Christmas either. What does the law say? how long can they string me along legally. Even if they made it a permanant layoff, nothing is preventing them from calling me when things pick up. How can I get my money, do they have a time limit? To me and everyone I've spoken to agrees that cancelling my health insurance is a good indication that they are through with me. Am I wrong?
