I'm lucky enough with my position that we have pretty well defined pay bands that mention our levels of knowledge, easily identifiable systems and managers that are basically expected to pay us to those bands when our knowledge increases. The one thing we don't have is enough time to effectively skill people up past a certain point. If you can spare the time, you basically will get promoted. We also have a lovely flex time system - work whenever between 7-6:30 as long as you hit 36 hours a week over 3 months, never heard of any pressure to come in early or anything like that with it either.
