Exxon Mobil will not allow corporate offices to fly the pride flag outside.

The Black Lives Matter flag and the LGBTQ-rights flag were banned by Exxon. Several employees at the company's headquarters in Houston, Texas were frustrated by the decision.

The PRIDE Houston employee group said in an email that corporate leadership took exception to a rainbow flag being flown at our facilities.

The members of Exxon's PRIDE group in Houston are refusing to represent the company at the Houston LGBT+ Pride Celebration in June.

The updated flag protocol is intended to clarify the use of the ExxonMobil branded company flag and not to diminish our commitment to diversity and support for employee resource groups, according to a statement from Exxon Mobil.

We are committed to keeping an open, honest, and inclusive workplace for all of our employees, and we are sad that any employee would think otherwise.

The company will allow employees to display flags with their logos. Exxon's policy allows employees to fly a flag that represents the company's PRIDE group, but that does not feature the company's logo prominently.

The members of Exxon's PRIDE Houston employee group said in an email that flying the Pride flag is a way for corporations to show their care, inclusion and support for LGBTQ+ employees.

It is difficult to reconcile ExxonMobil's desire to promote their corporation as supportive of the LGBTQ+ community outside of the workplace, but now that they believe it is inappropriate to show support for their employees at the workplace.

The company has a reputation for being behind on gay rights issues. Exxon eliminated Mobil's policies protecting employees from discrimination on the basis of sexual orientation in 1999.

Exxon amended its anti- discrimination policies to include sexual orientation and gender identity in 2015, according to the New York Times.
