PESP and other farces
PESP is basically a way of keeping industrial peace. Since your company has no union it cannot go on strike, therefore there is no risk of industrial unrest as long as the status quo continues.
Unless you and your colleagues join and union and this is recognised by management you will not be entitled to anything out of the partnerships wage negotiations. Many people get the impression that this is "given by the government" but not so. It is conceded by respresentatives of employers organisations in return for various things, such as promises for industrial peace, productivity increases and "modernisation." The sad reality is that of 1.8million employees less than 500,000 get this at all, yet its driven massive pay increases that have caused a huge percentage of employees to fall far behind in terms of increases.
This is further legitimised by IDA, who fund companies who are union-hostile, agressive cost cutters and often indulge in unfair and bad (though not illegal) employment practices. It ought to be conditional on companies who receive public taxpayers money and subsidies that they are subjected to these pay agreements. Otherwise we have the bizarre situation where an employer who has been on a wage freeze for two years with a huge number of workers on 68% of the average wage can win "employer of the year."
