I held a full time position, but was. Replaced by part time employees covering off the ame hours.

If you have a specific question, I would be happy to answer it for you. However, replacing your position with another worker is not, in and of itself, illegal, as long as you were not discriminated against in any way and as long as you are provided with the appropriate amount of severance. I recommend contacting an employment lawyer at the number below to discuss your entitlements.
