The only examples I can think of of large employers moving from Union & Management negotiated incremental based contracts to pay for performance & individual contracts are the major Banks.
This move unfortunately facilitated the abjectly poor lending stratagems over the course of the boom years which ultimately led to disaster as workers & management were financially incentivised & motivated into taking unacceptable risks.
As the movement to individual contracts was voluntary it actually removed the concept of meritocracy from such Banks as those generating large profits ( based as we now know on shifting sands ) were rewarded with promotion whereas as who remained on the incremental based contracts were seen as " stick in the muds " who were not incentivised to the same extent in the lending or investment arenas & as such were more likely to consider & apply good lending practices & ethics.
The downside for the workers on individual contracts was that of course they benefitted financially during the good times but as disaster struck bonuses ceased & they remain on a relatively low base salary compared to incremental contracts , this has had huge consequences for workers approaching retirement as their pension is based on final salary & their ability to generate large cash sums to help with retirement ended some 8 years ago , another significant factor was that overtime was not paid under such contracts.
A further downside is that poor management , personal dislikes , favouritism & a variety of human foibles can play merry hell with such a system.
Personally I opted to remain with the old Union negotiated scheme thus removing myself from the demands of an increasing demanding & capricious management team ( they were not particularly fans of Union members either
)
Now I do appreciate that all the above took place in a rabidly capitalist environment but perhaps there is a lesson there for any Government envisaging changing from a system that they can effectively control by such blunt instruments as the FEMPI legislation to an individual contract , pay for performance based system that they cannot control in such an arbitrary manner ?
Whilst an interesting debate the introduction of such a system into the Public Sector is , to say the least , extremely unlikely to happen.
