I think anyone striking at the moment is being shortsighted.
The jobs climate as it is I think they need to have some empathy with other workers, people with no pension plans, people who may have studied for years and have huge debts and the best they can hope for is a £13k paralegal job (I am in legal recruitment). And that entry level £13k paralegal job has been the same since I started in legal recruitment, so since 1999. And course fees and thus debts have gone up. Firms have people clamouring to work for free, and they do so, for years.
I honestly don't think that teachers are as poorly paid as other professions anymore, they're not. Lawyers/Accountants don't earn much, if anything more. They really honestly don't. Not in the regions, outside of the capital and even major city centres.
I advertised a v junior role and got people so qualified, I mean 3 degrees, exec level types applying. In fact for that one, poorly paid job I got 300 applicants. It's fucking tough out there and for people in jobs to be moaning about their pensions, when others have no jobs and are applying against 300 others? Shite.
