I don't want to copy anything onto here from the BASSA forum but let me tell you the "posting" (i.e. pro strike) membership are NOT IMPRESSED by these recent events. It turns out BASSA was not informed by Unite about these talks, which started on friday, until today!
Remember, once a strike is called only BASSA (not Unite) can call it off. As the BASSA reps have made it clear that they prefer an "all-out" indefinite strike, this can't be an easy decision for him to make.
In my opinion, Unite has realised that this is a lost battle and the only thing to recover anything from the previous offers is to sit down and not let BASSA implode after a few more days of industrial action.. I think he's doing them all a big favour.
