Following a holiday lull, Hercules Aerospace resumed its "right-sizing" program Friday with the layoffs of 20 full-time and 35 temporary employees from its Bacchus plant.

A total of 287 Hercules workers have lost their jobs since October, and a company spokesman said additional reductions are expected sometime after the first quarter of the year."These right-sizing efforts will permit Hercules to better position itself in an increasingly competitive world aerospace market," the spokesman said.

The 20 full-time employees who lost their jobs on Friday worked in the space/strategic propulsion section.

In addition to the workforce reduction, the company is streamlining processes, reducing bureaucracy and decreasing indirect costs, the spokesman said.

Hercules Vice President and General Manager Ron Peterson said, "These initiatives will help us to ensure a strong industry position for the Bacchus Works and jobs for tomorrow."
