North Reading's Public Works Department is short 10 of its 25 employees, as the result of a drug probe that has led to one arrest and the resignation of the department head.
In total, three public works employees have resigned. Seven have been placed on leave during investigations related to opioid possession.
Briefing reporters Wednesday, North Reading Town Administrator Michael Gilleberto said those who are left will take care of core services.
"At this point in time they're going about their work, trying to fill in the gaps and maintain services for our residents," Gilleberto said.
A DPW subcontractor also faces charges of possessing Oxycodone with intent to distribute. One of the suspended employees is charged with possession and conspiracy to violate drug laws.
