Yes, a big but in my mind is that the problems in the Post Office could so easily have been avoided.
In great part the problems have been caused by the government insisting that the UK postal market be opened up to foreign competition whilst many of the countries the foreign companies are from do NOT open up their own services. In much the same was as it is very difficult now to find a UK company that provides water, gas or electricity because they have been bought by foreign companies whose home markets are still monopolies, the same is happening to the postal service.
The changes the Post Office need to go through do not have to be so quick and so radical and were it not the need to change so quickly of be made extinct by foreign companies who offer few benefits to their own workers, the Post Office's change could have been evolutionary and not revolutionary.
Of course, the proposed changes to the Post Office Pension scheme might have been avoided if the post office had not taken a seventeen year pension holiday on its pension fund (not this was started under the Tories and continued under Labour).
However, given where we are at, I cannot see hoe striking will do anything other than play in to the hands of the Post Office's foreign rivals but I accept at the same time that if I were a postal worker and they were threatening to cut my pension then I would probably go on strike too.
