Nearly 10,000 Philadelphia city workers, primarily represented by AFSCME District Council 33, are on strike demanding better pay and improved work conditions.
The rapper announced his decision via Instagram, emphasising his refusal to perform for money while people are fighting for a living wage, though he will still be in the city.
The strike, which commenced earlier in the week, has seen negotiations between the city and union leaders stall, with no immediate new talks scheduled.
The union, representing a majority of the city's blue-collar workforce, is also seeking flexibility on the city residency requirement for employees.
