Brazilian metalworker Andrea Eloisa da Silva had been embarrassed one too many times by her boss, who made "dumb blonde" cracks about her in front of co-workers.
She sued him and not only won $1,300 in moral damages, but also recognition that she had been unduly fired - which paves the way for more compensation.
"It is an unprecedented decision on moral damages for blondes," Alexandre Santoro, a spokesman for the regional labor court that ruled in Silva's favor, said on Tuesday.
The judge, he said, "determined that the term 'dumb blonde' violated the dignity of the employee.''
The owner of the Usinagem RPM metal factory, where Silva, worked can appeal the ruling.
As in the English-speaking world, there are an unending number of jokes about "louras burras'' or dumb blondes, in Brazil.
