Honestly, I don't see how having "better academics" is a good indicator of teaching quality. If anything, they'd be more concerned with they own work anyway. That's the truth about tertiary studies - why do you think teaching quality will change if they get more job security? If anything, it will have the opposite effect.
Don't call me naive but if there's no dire consequences if you don't do your job, you won't do it. In this case, doing a shit job without any consequences is a recipe for carelessness. Honestly, pay and job security is VERY GOOD at USyd - casualisation of jobs is NOT unfair. Sure, you don't get sick days and annual leave but you get a good 25% casual loading. Is that not enough?
Don't tell me that it's fighting for my future - that's a load of shit. There's reasons why teachers here don't give a fuck and it's because there's no benefits in their undergraduate students perform well.
Right now, striking further has proven that this is more of a problem to education at USyd than what you want. We have missed around and 5% of our time and we are paying for these actions.
This striking is not about students education quality, it's about personal benefit of USyd staff. Stop wasting our time and do your job - if you don't like your working conditions, find a new job.
