Brake light doesn't go off!!!

I had the rear brakes changed last month(rebuilt calipers, two new rotors and new brake hoses). Ever since then my e-brake light stays on all the time. I've seen posts here about it, and I've tried the disconnecting ground(for 2 days) and the one with the clock, but nothing has worked. Can anyone suggest something that I can try? Thanks!
