Furious Duke University students call for school's executive vice president to be fired over claims he called black worker a 'stupid n*****'

Outrage sparked by allegations that Duke University's executive vice president called a worker a 'stupid n*****' showed no signs of abating week as students at the university continued their week-long sit-in demanding that he be terminated.

The friction began when Shelvia Underwood, a parking attendant, filed a police complaint saying that Executive Vice President Tallman Trask III had hit her with his car before a Duke football game in August 2014 before calling her the racial slur, AOL reported. 

Appalled students then occupied the building that houses Duke President Richard Brodhead's office on April 1, issuing a list of demands that Brodhead tried - and failed - to meet Wednesday.

Refusal: Students at Duke University organized a sit-in on April 1 demanding that Executive Vice President Tallman Trask III be terminated for allegedly calling a worker a 'stupid n*****' in 2014

Target: Trask (pictured) denies that he used the racial slur, but admits being 'impatient' in the encounter. The worker has also filed a lawsuit against him

The students made a list of seven demands, including not just the termination of Trask and two other university employees, but also a series of reforms, including the increase of the minimum wage for workers to $15 per hour by 2019.

According to The Duke Chronicle, Brodhead sent an email at 6.20pm Wednesday announcing that the university would get independent expert advice to review the university's complaint procedures, and would raise the minimum wage to more than $12 per hour.

It took the students just half an hour to discuss and reject the demands, reported Associated Press.

'While we are pleased that the administration has returned to the table, we believe actions are too vague, non-committal and non-comprehensive to be sufficient for exiting the building,' said Danielle Purifoy, a PhD student in environmental policy and sit-in organizer told The Duke Chronicle.

That decision did not go down well with the university. Michael Schoenfeld, Vice President for Public Affairs and Government Relations, told the Chronicle in an email: 'We offered to negotiate if they left the building. That didn’t happen, so we're not negotiating and we’re done with demands.'

The students did, however, make modifications to their demands Wednesday.

They originally made seven demands of the university, starting with 'the immediate termination, without compensation' of Trask, Vice President Kyle Cavanaugh and Parking and Transportation Services (PTS) Director Carl DePinto.

On Wednesday they announced that this demand would be negotiable.

Demands that the university review of employment standards for sub-contracted workers and give 'community input' on the selection process of Duke administrators were also deemed negotiable.

They also wanted Trask pay full legal and medical reparations to Underwood, but this was dropped on the understanding that a lawsuit already filed by Underwood would deal with this.

Other demands remain: an apology from Trask to Underwood and other PTS employees for what they describe as 'hateful, violent, negligent actions, a demand that an outside council examine goings-on in the university, and that minimum wage to be raised to $15 by 2019, and tied to inflation.

They also announced that they would leave the building if two demands were met, but only if negotiations continued within a week of them leaving. 

'The car accident was just kind of the top of the iceberg,' Purifoy told AOL.

'We wanted to utilize this incident to highlight not just the egregious nature of the incident itself but the larger pattern of discrimination aimed at workers of parking and transit at Duke.'

Trask has apologized for the incident with Underwood, but denies that he made a racist remark. 

'I very much regret the incident before the Elon football game,' he wrote in a note obtained by the Duke Chronicle. 'I should have been more patient and I apologize.'

Angry: Even an Italian instructor (pictured, center) has joined in the protest. The students also want the minimum wage raised to $15, and rejected a proposal to increase it to 'more than $12' on Wednesday
