MINNEAPOLIS (WCCO) — On Tuesday the Science Museum of Minnesota announced that it will shift to online-only programming, and temporarily lay off 400 of its employees.

The layoffs will leave 87% of the museum’s staff out of work for the time being amid the coronavirus (COVID-19) outbreak in Minnesota. A small number of people will continue to work to provide online programming, as well as security and maintenance.

CEO Alison Brown released a statement on Tuesday:

Closing was the right decision for the health and safety of our employees, volunteers and visitors, but it is creating a financial hardship during our busiest time of the year. Temporarily laying off employees was a tough decision. It is unfortunately necessary as we consider the long-term viability of the museum.
