Let go out of the blue after being a part-time abstractor for 6 months. Literally had a 1 minute 48 second call from my manager that said we are letting you go. They sent me a generic letter that had someone else's name on it which makes me think it was a mass exodus of part-time employees. I emailed the CEO and VP and never got a response. Be careful working for a company that will dismiss employees like this without any explanation.
