Short answer - I don't support the strikes, no.
Long explanation as to why!
In my previous existence, I worked in the private sector, and I lost my 'gold plated' final salary pension scheme after five years service because it was unaffordable; the benefits were amended to a defined benefits scheme after I had already signed up for my then industry standard final salary scheme. I don't have a union, and I couldn't strike - just try and work harder and for longer to make up the shortfall. (As I'm now a SAHM for the time being - the pay is atrocious and I don't suppose we're going to get a state pension....so I'm in serious trouble until I go back to work!).
There is a demographic timebomb - too few workers will be supporting the pensioners of tomorrow and people in whichever sector they work will have to face up to the reality that they will have to work longer, because we are all living longer. This isn't a new situation - we used to have an envied pension sector in this country, but Gordon Brown made changes which raided pension funds to raise taxes, and decimated the surpluses that many had built up. He created a completely bloated welfare state which has made working less attractive than being on benefits, so there are fewer economically active people supporting the pensioners of tomorrow who have never done a day's work in their lives.
Yes, the economic downturn hasn't helped, and the lack of jobs (for young people in particular) is terrible, but the previous government helped to create this mess by not making hard decisions earlier, and in any case, for political reasons, a Labour government couldn't be seen to be damaging the 'workers' I imagine.
Most public sector workers, (even the lower paid ones) will be better off than those of us in the private sector who are unable to put enough money into our pension schemes because we're now having to pay for our children's university education, to find money to help them get a roof over their heads (even just putting together a deposit to rent, let alone helping with a mortgage deposit!) and to pay for care for our parents, and ourselves in due course - along with having to pay to keep roofs over our own heads - which in the SE is a far higher burden than it should be, due to house prices having been held artificially high for so long.
I think that the strikers are irresponsible to strike. For a start, they barely have a mandate as the turnouts were so low - most strike ballots were with a turnout well below 50%, and talks are still ongoing - surely it would be better to wait until there is absolutely no further room for negotiation?
