City College of San Francisco trustees quietly doubled the salaries of several executives and approved double-digit raises for others this summer, budget documents show, even as the school slashed hundreds of classes and let go of faculty and counselors to close a $32 million budget deficit.

“Shame! Shame!” cried more than 100 students and instructors Thursday as they stormed the office suite of Chancellor Mark Rocha, who was nowhere to be found. “Shame on the Board of Trustees! Vote them out!”

The elected Board of Trustees approved the new compensation on Aug. 22, as part of the final college budget for 2019-20. The executive raises took effect in July, and appear deep in an appendix of the 105-page budget. Here are the details:

• Vice chancellors with a starting salary of $124,358 last year will now start at $250,000.

• The top salary for vice chancellors rose 23%, from $210,895 to $260,000.

• The trustees created an executive layer — senior vice chancellor, with pay ranging from $275,000 to $285,000. Three former vice chancellors were elevated.

• Pay for associate vice chancellors doubled at the low end, from $113,878 to $228,000, and rose by 23% at the high end, from $193,125 to $238,000.

• Deans got a 90% raise at the low end, from $108,975 to $208,000. At the high end, the trustees awarded an 18% raise, from $184,809 to $218,000.

College officials did not say how many executives are at each level.

Three of the seven trustees responded to a reporter’s request for comment. One, Ivy Lee, who left the Aug. 22 meeting before voting on the budget, declined to discuss the raises but said: “I had strong concerns about the process.”

Two declined to comment. One, Shanell Williams, is a former student leader at City College who led fiery protests against budget cuts during the campus’ five-year struggle to retain its accreditation between 2012 and 2017. The other, Tom Temprano, said Wednesday he was out of the country. The others did not respond.

A beneficiary of the new compensation levels — Dianna Gonzales, senior vice chancellor of administrative and student affairs — issued a statement defending the raises on several grounds, including that one administrator had threatened to sue the college if the money wasn’t forthcoming.

Referring to the executive raises as a “salary correction,” Gonzales said the raises put the recipients “well within statewide standards for each administrative job category” and cited a 2017 compensation survey of California college administrators.

A look at the survey shows that not all job categories are comparable to those at City College. But the median salary for chief executives of single districts, as City College is, was $235,786, nearly 6% less than the new starting salary for a City College vice chancellor.

Gonzales justified the increases in part because City College administrators “are in service 52 weeks per year” and work a lot of overtime. Their workload has increased because 25% of the 76 administrators employed last year have left, leaving 57.

Meanwhile, City College is offering 10% fewer classes this fall than last — a reduction of 242 classes in a range of subjects, from the natural sciences to ethnic, women and LGBT studies, school officials said.

The school also reduced the number of counselors, faculty and staff through layoffs, non-renewal of contracts, and buy-outs, but did not provide specific numbers despite several requests.

The college is still trying to add thousands more students to its enrollment of about 70,000. The effect of that, faculty say, is to pack their classes and overload counselors.

On Thursday, the confluence of problems reached a boiling point among students and faculty.

“This is a crime!” student Winmon Kyi cried into a megaphone as she addressed the protesters from the staircase leading up to Rocha’s office in Conlan Hall.

“We are furious!” said Jenny Worley, president of the American Federation of Teachers Local 2121, which represents faculty. “Raises up to $100,000 while we’re laying off faculty and cutting classes and counselors!”

The crowd booed.

College officials have said for more than a year that they will eliminate under-enrolled classes, such as those with fewer than 20 students.

Student Vickie Chung became incensed in July when she got an email from faculty saying that several courses — including one she needed this fall for her major in sexual health — would be canceled in a week unless 20 students could be rounded up to enroll.

“I dropped everything and started organizing,” Chung told the crowd, her voice breaking with emotion. “And they’re here giving themselves raises? They cannot siphon money away from us!” she called, as the crowd chanted: “Students first! Students first!”

Chung founded the group CCSF Collective, which succeeded not only in rounding up enough students to save her class and others, but helped a number of other frustrated students go through registration.

In May, Rocha appeared before a hearing of the San Francisco Board of Supervisors and the City College trustees to explain the course cuts to city officials.

“Many of you have heard about the $32 million budget deficit — and it’s real,” Rocha told the committee.

But this week, Rocha’s chief of staff, Leslie Milloy, said, “There is no budget deficit.” She credited the trustees with approving the college’s “first balanced budget in more than 10 years.”

A look at the 2019-20 college budget shows that the general fund is nearly $2 million in the black. Reserve funds sit at $11 million, about half of what they were last year.

Total revenues, however, fell $53 million short of the $301.5 million it spent.

Students and faculty are demanding that the trustees rescind the raises, bring back laid-off faculty and restore canceled classes.

The trustees’ new budget committee is expected to meet at 9 a.m. Thursday to discuss the raises, Milloy said. A location has not yet been set.
