"It's bad. I've been with the agency for over 33 years and I've never seen anything like this," said Marie Owens-Powell, president of the union that represents more than 8,500 EPA employees.

Over 1,000 workers at the Environmental Protection Agency (EPA) received a letter from the agency warning they may face termination as probationary or trial period employees.

More than 1,100 employes at the Environmental Protection Agency received notice this week that they were deemed to be on probationary status and warning they could be fired immediately, according to an email obtained by CNN.
