AKRON, Ohio — The Akron Art Museum, adjusting to harsh new realities caused by the global coronavirus pandemic now hitting the U.S., said Monday it was closing at least until June 30 and is imposing furloughs, pay cuts and other changes to adjust to a sudden drop in revenues.

Mark Masuoka, the museum’s director, said the institution anticipates losing as much as $933,000 in the fourth quarter of its fiscal year ending June 30 or nearly a quarter of its annual $4.2 million budget.

The losses will come from the sudden disappearance of an estimated $329,000 in earned income from admissions, facility rentals, and store and café sales. The museum also anticipates losing memberships and donations worth another $600,000.

Masuoka said Monday afternoon he had just gotten off the phone after speaking with 35 employees to tell them about pay cuts, furloughs and reclassifications of employment.

“It’s the worst thing a director can imagine doing,” said Masuoka, who previously led art institutions in Omaha, Nebraska; Las Vegas; and Denver.

“I’ve been around for 30 years, and I’ve had to navigate these [economic] downturns,” he said. “This is like nothing I’ve ever experienced. There are so many unknowns. That’s what makes it so disturbing.”

The museum, which employs a full-time staff of 35, announced Monday it is imposing a 10% pay cut on six department heads, including Masuoka, plus a 5% pay cut on roughly another dozen. Another dozen employees will be reclassified from full time to part time, but will retain full health care benefits through June 30, Masuoka said.

Several other employees will be furloughed.

“The financial piece is just heart-wrenching, especially when it impacts my staff,” Masuoka said. “It is truly one of the hardest things I’ve ever had to do.”

He said the museum is trying to keep the staff intact as a team, and is preparing to reopen at an unknown time in the future.

“That’s the main focus of our conversations,” he said. “It’s trying to do it as quickly as possible, but not having control over when that is — that’s the hard part.”

The Akron museum, which received global attention in 2007 for an architecturally ambitious expansion and renovation, has performed solidly under Masuoka, who became director in 2013.

The museum has attracted nearly 80,000 visitors a year with eye-catching exhibitions, on the costumes of Nick Cave, the sculpture and paintings of June Kaneko, and art inspired by video games. It has also received major grants, including $8 million in 2017 from the Knight Foundation, the biggest in its history.

In 2016, it completed its Bud and Susie Rogers Garden, one of the most beautiful new outdoor spaces in Northeast Ohio.

Like other art museums around the world, the Akron museum is migrating its programs online. And it is thinking about what life looks like post-shutdown, both for the institution and for its community.

“No matter what the restrictions are, this is a definitely a psychological thing,” Masuoka said. “Just because you’re told the coast is clear doesn’t mean people will go back to their old habits.”

He said the museum hopes to open this summer. But at this point, he said, “That’s purely speculative.”
