I tried playing hardball with my manager last month and it didn't go the way I'd hoped. I walked in ready to threaten leaving if they wouldn't bump my pay, but I didn't actually have another offer lined up. My manager basically called my bluff on the spot, told me if I wasn't happy I knew where the door was, and now things between us are awkward as he-l.
What are my chances of being outright fired over this?
