Well, I'm no expert on inflation, but it's my understanding that whenever inflation is high, unemployment is low. Vice versa, the same is true too (unemployment high, inflation low). I vaguely remember my Grade 10 SOSE class last year, in it we learned about 'Phillips (spelling?) Curve'. Phillips Curve is what I just mentioned in graph form. Ofcourse though, thats only short term. In the long term there is no relationship between unemployment and inflation.
Hope I helped.
