Awesome, looked it up on Wikipedia. Strike was actually three separate strikes, just over one year in total duration. Dates as follow:

May 7 – July 30, 1966

May 1 – November 17, 1970

June 28 – September 6, 1976

According to Wikipedia[1], the banking strikes had little affect on the preexisting economic woes, namely both high unemployment and inflation.
