Under the ban being considered by Landskrona in southern Sweden, city staffers would not be allowed to go onto the street during group coffee breaks that are common practice in many Swedish workplaces, the Swedish news agency TT reported Friday.
The ban would cover employees working in open spaces and even working from home.
One supporter of the proposal said working hours "should be completely free of tobacco."
A member of the city's environmental committee criticized the initiative.
"Moralistic and ridiculous," Hogni Hansson said.
"Smoking is dangerous but I wonder just how far an employer's powers stretch," he said.
Several cities in Sweden have already introduced a blanket smoking ban on employees during working hours.
