I've seen both sides so far.
Suffice to say that I work in a specialised industry where there just aren't suitably trained people available who aren't already employed. Bottom line is that my employer actively encouraged me to join the union (which I did, never been in a union at all until 3 months ago). As far as I can determine, the reason is that they are less worried about a 40% pay claim that the union is pursuing than about the prospect of workers leaving and thought that being in the union would encourage people to stay. Management has gone as far as to authorise use of resources, vehicles, paid time etc for union matters as long as there is at no point a complete stoppage of work. That is, they're happy to pay wages during union meetings etc as long as enough people remain at work to maintain the appearance of normality. The lost time has, in practice, been made up with paid overtime at penalty rates without question.
2. Mobil is pulling out of running service stations in Tasmania with their sites being acquired by an non-major oil company operator under it's own brand. They have cut the wages of workers, something that has received considerable publicity. I won't be buying fuel from them.
Bottom line seems to be that those with in-demand skills have basically got a blank cheque now more than ever whilst those without such skills had better get used to earning about $28K working full time regardless of when (day, shift, weekends etc) they actually work those hours.
Average wages seem likely to continue to rise but with an increasing gap between rich and poor defined not by formal qualifications but market demand. If the job can be done by anyone with minimal training or there is a large pool of suitably trained people then look out below as far as wages are concerned. If it's specialised then you don't have too much to fear
until the next recession at which point I think we'll see the real effects of the new laws prolonging the slump as workers accept pay cuts in fear of losing their jobs.
A way of increasing the boom and deepening the bust IMO. History will judge it harshly.
