Despite having never made any claim about teacher salaries in union versus non-union environments, I’ll provide a little bit of data.
The following States do not have teacher unions at all:
Georgia
North Carolina
South Carolina
Texas
Virginia
cite shows unionization rates by State. Various resources say that the above following States do not allow teachers to be in unions, although if you look at the unionization rates most have some % of unionization (other than South Carolina, which has 0.0%)–I do not immediately have an explanation for the discrepancy but will note that either way these are five states with extremely low or no unionization of teachers.
Here is the average pay per state:
Georgia $48,300
North Carolina $43,922
South Carolina $43,011
Texas $41,744
Virginia $43,823
Now I could just start pointing to all the states with lower pay than these 5 as proof that unionized labor can make less than union labor, but that’s not really demonstrative of anything.
Instead I’ll compare CPI numbers from a few selected cities (if you know of statewide CPI numbers available from the BLS, let me know, I couldn’t find any.)
Georgia has an average teacher salary of $48,300 and virtually no unionization.
Florida has an average teacher salary of $43,302 and is 100% unionized.
Atlanta, GA has a CPI in Feb of 2012 of 210.26.
Miami-Fort Lauderdale, FL has a CPI in Feb of 2012 of 232.60.
So here we see a State with a higher cost of living (Florida > Georgia) that is 100% unionized, and pays its teacher’s less than a non-union state. These aren’t teachers in special schools that require extra work, but aggregate data involving public school teachers in general.
There’s also little difference in benefits that seem to correlate to unionization.
Georgia teachers receive tenure after 3 years, which many alarmists would say teachers would not even receive without a union. Florida teachers receive tenure after 3 years as well. In Florida, the firing rate for experienced teachers is 0.36%, for experienced teachers in Georgia it is 1.36%. So that’s obviously higher, but don’t look for a trend.
In North Carolina with virtually no-unionization they get tenure after 3 years and have a 0.6% firing rate of experienced teachers. In Ohio with almost full unionization they get tenure after 5 years and the firing rate for experienced teachers is about 1.91%. In Wisconsin with almost full unionization and 3 year tenure, they fire experienced teachers at a 2.14% rate.
