Medtronic (NYSE:MDT) is reportedly planning to lay off nearly 100 more workers at a plant in California over the next four years as it moves the operation to Massachusetts.

The Santa Rosa plant, which makes catheter components, was hit by a wildfire in October 2017. Last April the Fridley, Minn.-based company told employees there about 85 to 100 pending job cuts from departments including R&D, operations and marketing.

The latest round of layoffs are part of Medtronic’s plan to shift the work to a plant in Danvers, Mass., spokeswoman Wendy Dougherty told the Santa Rosa Press Democrat. Employees whose role is being eliminated are due bonuses if they agree to work through May 2020, Dougherty told the newspaper.

The Santa Rosa plant is the sole manufacturing operation for Medtronic in Sonoma County, but the cuts won’t affect the other roughly 1,100 workers in its coronary & structural heart and aortic, peripheral & venous businesses in nearby locations.

“We will maintain our significant presence in the area with our Fountaingrove and Brickway facilities,” Dougherty told the paper via email.
