180 day rule re green card approval?

I am working for a UK company in the US and have been in NY with an L1 visa since September 2001 with my family. The company's immigration lawyer filed an I-140 and I-485 last May and we are waiting for green card approval which we are told we should receive in about a month's time. I have heard a strong rumour that I could possibly lose my job soon. We are an 'at will' company so it is easier to be let people go without reason. Once we have green card approval, can I get another job in the US or do I lose residency status? Once we are approved do I still have to stay with my company for 180 days before getting another job or is it 180 days from filing?

Answer:
So many questions. It is your livelihood and quality of life you are talking about - why are you looking here? invest in yourself and contact a competent immigration attorney.
I have to agree with Curious on this. You would be well served to contact a good immigration attorney and many will give you a free consultation too.
Definitely get an immigration lawyer. This is too big an opportunity to miss. Do you have copies of the paperwork that has been filed? Your lawyer will benefit from seeing those.

Once you get the "Temporary Green Card" stamp in your passport you are here legally and have the same rights as any other Lawful Permanent Resident.
