Several hundred forensic police, many in white lab coats and blue gloves, took part in the demonstration on Wednesday, displaying banners and placards proclaiming “I am a cop”, and “My job is not dangerous, that's why I have a bullet-proof vest.
Several dozen protesters lay on the ground posing as blood-spattered corpses amid a field of fake severed arms and legs, a scene that a banner proclaimed as “Our daily reality”.
They complain of being denied benefits enjoyed by their armed police colleagues, who have an “active” employment status while they are categorised as “sedentary”.
Active police members qualify for earlier retirement.
“We have an ambiguous status even though the majority of people here… have been confronted with criminals, and regularly see corpses,” said one protester who carried a sign around his neck stating: “Charlie Hebdo, I was there too” in reference to the deadly 2015 attack on the Paris-based satirical magazine.
The job is “extremely difficult” with “many strains”, said Soazig Henrio, of the Snipat union for forensic and scientific police.
“We want the danger and the difficulty of our work to be recognised,” she said, as other protesters held up posters declaring: “Have you ever slipped on the bodily fluids of a putrified corpse? I have.”
