Within the email, Shotwell confirmed the “termination of a number of employees” involved in creating the letter.
“The letter, solicitations and general process made employees feel uncomfortable, intimidated and bullied, and/or angry because the letter pressured them to sign onto something that did not reflect their views,” Shotwell wrote.
She also said that the company has “too much critical work to accomplish,” and there was “no need for this kind of overreaching activism.”
Shotwell added: “Please stay focused on the SpaceX mission, and use your time to do your best work. This is how we will get to Mars.”
Musk has been a bit unpredictable for a while but has since proposed the acquisition of Twitter in April.
