scoped thread wrapper for std::thread

I am trying to make a scoped thread.

#include <iostream>
#include <thread>

class ScopedThread {
 public:
    template< class Function, class... Args>
    explicit ScopedThread( int id, Function&& f, Args&&... args)
        : m_thread( std::ref(f), std::forward<Args>(args)...)
        , id(std::move(id)) {
    }



    int getId() const { return id; }

    ~ScopedThread() { m_thread.join(); }
 private:
    std::thread m_thread;
    int id;

};

class Worker {
 public:
    Worker(int id): thd(id, &Worker::work, this) { }

    void work() {
       for( int i = 0; i < 10; i++)
        std::cout << "I am working" << std::endl;
    }


 private:
    ScopedThread thd;
};

int main() {
    Worker(1);
    Worker(2);
    Worker(3);
    Worker(4);
}

When I run the code, it dumps core.

Can someone tell me how do I forward member functions and arguments to the underlying std::thread class ?

My objective is to make the wrapper class completely replaceable with std::thread class. Wrapper class takes a new argument for thread id.
