Hi,
The link you provided is a fairly obvious fake by a "contractor". Uh...that is not the correct terminology. Teachers never refer to themselves as "contractors" in my experience. Technically, yes, teachers work under a contract for one year.
Here is another small example:
Pay teachers better, pay classified better. North Slope has the highest teacher (and classified) pay scale in Alaska. Probably one of the very highest in the entire nation.
And:
Teachers are hired with a stated contract amount, but when they report to work, a salary adjustment is made on their contract, and they are paid less.Placement on the salary scale is also most determined by statute - i.e. number of years of prior service credit allowed for teachers new to the state, etc. - and is done by the HR department upon evaluation of teacher credentials. There is not a great of deal of "adjustment" that can be made, as the union contract specifies the pay based on number of years experience (up to the maximum allowed for Bachelor's / Master's / + X credit hours on transcripts). It's pretty clear formula.
Here is another example:
Begin late hire teachers their tenure the day they are hired.In all Alaska school districts teacher tenure is governed by the state, not by school districts. Tenure is acquired by a very specific formula, and is "portable" in some instances. All of this is determined by the Alaska Statutes, and districts can't have their own policies or provisions for providing tenure rights. Bzzzzzz. Thanks for playing.
AS 14.20.150. Acquisition and Reacquisition of Tenure Rights.http://www.touchngo.com/lglcntr/akstats/Statutes/Title14/Chapter20/Section150.htmMoney that teachers should be paid is never paid without a major issue being raised.All districts in Alaska have negotiated agreements with their teacher's union that determine pay and benefits. They have a bargaining unit, and the latest contract was just last fall. District business offices simply direct deposits (in most cases) all teacher salaries in 12 monthly (or in some cases 9 equal) installments. Works like clockwork once you set it up at new teacher in-service.

Here is the NSBSD Negotiated Agreement download page, with salary and benefit facts and logistics:
https://www.nsbsd.org/Page/4242This is not an endorsement of NSBSD itself, so much, as me just letting you know how it is with teacher salaries and district business offices. I'm pretty sure that the "contractor" in question was not likely an actual employee writing about the district....in my opinion.
Hope this helps,
John
