More than 1,100 staff members at the Epa received notification this week that they were considered to be on probationary status and alerting they might be fired immediately, according to an email obtained by CNN.

Probationary staff members receiving the email have been operating at the company for less than a year. The emails began to head out late on Wednesday afternoon, according to an EPA union official.

The very same message will be sent out to other firm labor forces, a White House authorities said. Across the US federal government, the current data shows there are more than 220,000 staff members on probation.

"As a probationary/trial duration staff member, the firm can instantly end you pursuant to 5 CFR § 315.804," the EPA email to probationary workers checks out. "The process for probationary elimination is that you get a notice of termination, and your employment is ended immediately."

"Each staff member's status will be identified individually," the email includes.

The email likewise spells out an appeals process workers can take to see if they are qualified for extra security.

The approach is similar to how Elon Musk, now a key Trump adviser, dealt with layoffs when he bought Twitter - make a brand-new e-mail alias (in this case, notice@epa.gov) and then send mass termination letters to everybody on it.

The US Office of Personnel Management declined to comment, and the White House and EPA did not respond to requests for extra remark.

The EPA union official said these probationary employees aren't the exact same as at-will workers
