An interesting corrective to the notion that public-sector wages in Alberta are rising twice as fast as the national average can be found here. In fact, Alberta public-sector wages are rising at roughly the rate of inflation (just like most other provinces)—it is the overall wage bill that is growing quickly.
Among the factors driving this are executive perks that few public sector employees see. One observer has suggested that the authors did not account for the effect of inflation on earnings growth (i.e., they are not using constant dollars) which, consequently, overstates the growth quite significantly
