The 25-year-old has struggled in recent seasons to reproduce the form which brought him over 100 first-class wickets across the 2007 and 2008 seasons and earned him 10 limited-overs international caps.
The Tykes won promotion from LV= County Championship Division Two last season but Rashid took only 16 wickets at an average of 41 and made 129 runs at just over 16. "I've been playing here seven years and I want to stay," he told the Independent. "But I have a career and I can't waste another year."
He added: "If I don't feel as though I've been treated well, I'll go. It's hard to come straight on and hit your length and line with every delivery if you're hardly bowling and the coaches and people around you don't give you the backing.
"Obviously there's some blame on me but there's some on the people around me, on the captain and the coaches. The captain knows what I can do because I've got 200-plus (296) first-class wickets.
"He should have thought: 'Okay, he's done this in the past, I need to back him.' If I don't get that from the captain obviously my confidence is going to go down.
"(Michael Vaughan) used to set defensive fields and just bowl me. He never doubted me and it would just build my confidence, I'd get a wicket, get another, get four, get five.
"With Galey it's changed. A couple of overs and that's it, you're not bowling again for a long time, and when you do come on to bowl again, it's for an over. I don't think it's fair."
