Hundreds of Oracle employees walked out of work in protest of Chairman Larry Ellison’s decision to host a fundraising event for President Trump.

The protest, called No Ethics/No Work, involved about 300 employees walking out of the office or stopping remote work at noon local time Thursday and devoting the rest of the day to volunteer work or civic engagement.

A Change.org petition was started almost immediately after it was learned that Ellison would be hosting Trump, and it received over 8,000 signatures by the time of the walkout.

“For me, opposition to Trump is no longer a matter of political viewpoint, of disagreeing with his mostly awful policies,” an Oracle developer tweeted Wednesday. “It is a matter of whether you believe in the rule of law.”

Petition organizers insisted that Ellison give money to humanitarian causes such as climate change, diversify the company board, and publicly denounce the Trump administration.
