Some do, MOST don't...
To be completely honest mate and i've asked a few other guys as well most of us don't actually know what the current rate is as the idea of doing any overtime in the current climate is pretty unattractive. There isn't much goodwill amongst the pilot workforce at the moment unfortunately.
Someone will dig it out for you eventually but Eye Off The Ball's view is shared by myself and most of our colleagues.
Cheers
