Although the class was designed for public school cleaners, all of the union''s 70,000 members are encouraged to partake in the seminar, the story stated.
Instructors prepared the cleaners for what is widely expected to be a resurgence of the virus that infected many in the spring and has continued to cause havoc for many.
Local 32BJ Secretary Hector Figueroa said: "The idea is that if we do this, then we help support the programs put in place by the city and by private employers to make sure that New Yorkers are protected and that our members are able to do their job of protecting others."
To the surprise of some attendees, the majority of advice was commonsense prevention like proper hand washing and continuing a cleaning program focusing on high-touch surfaces, the story noted.
The union is hosting three more training sessions on Saturday and plans to continue offering classes as long as the pandemic poses a public threat, the story added.
