The last contract expired Oct 2022. Negotiations by then had already reached the point of agreement as to annual wage increases -- outstanding issues mainly involved benefits like paid vacations and paid sick leaves. As to the increase in wages for 2023 , those were already built into the 2023 dues that came in Dec, and were the main reason for some substantial increases seen with the 2023 dues. Further increases will occur annually as wages increase annually and as other costs increase annually due to the modern, galloping inflation rate, but employee costs are the majority of operation costs.
Note, that the new contract is between the main Walt Disney World Co. and the unions. Almost all those employees you see providing maintenance and services at the resorts, and providing transportation, are employees of the main Disney World company and not employees of DVC. DVC, under agreement with the main Disney World company, pays a share of those employees costs to that company.
