Employee at apartment complex terminated/evicted
My mother works at an apartment complex in Missouri. She has been there for 3 years through 3 different management companies. On 5/20 she was recently terminated along with two other long term employees. Before they told her that she had been fired, they asked her to sign a lease for the upcoming year. They told her that she would have 30 days to decide if she wanted to terminate the lease or continue renting her apartment at full cost. They came to her today and told her that she didn't have 30 days, that she had until the end of the day on 5/31 (today) to remove her belongings and relocate or pay $750.00 to stay. I was under the impression that they needed to give 30 days from the date of termination as a move out date. Is this true?
