Nearly 41,000 people have signed onto petitions asking Senate Republicans to back a bill that seeks to ban workplace discrimination based on sexual orientation and gender identity.

The Employment Non-Discrimination Act (ENDA), which was first proposed in 1994, cleared a Senate committee with the help of three Republicans in July and is expected to reach the full Senate on Monday.

A petition organized by progressive group CREDO had attracted more than 38,500 signatures as of Friday.

“Senate Republicans: Discrimination against gays, lesbians, bisexuals and transgender people at work is not just wrong, it's un-American,” the online petition reads. “The Employment Non-Discrimination Act (ENDA, S.815) will come up for a vote soon, and now is the time to support equal rights at work and come out in support of the bill or at least refuse to filibuster it.”

Another 2,400 people backed a similar effort.

“Put a stop to employment discrimination based on sexual orientation or gender identity,” the petition reads in part. “Pass the Employment Non-Discrimination Act!”
