When the private equity firm BC Partners bought PetSmart in 2015, animal deaths more than doubled and working conditions plummeted.

PetSmart workers are organizing with United For Respect for safer conditions for pets and employees.

The company’s behavior under BC Partners has caught the attention of Senator Warren and Rep. Mark Pocan, who are demanding answers about working conditions and pet deaths. Their bill, the Stop Wall Street Looting Act, would hold private equity firms responsible.
