Tucson Unified School District is prepping for a possible strike by Sun Link workers that could affect a couple thousands district students.

If Sun Link and the transit union do not wind up with a contract, the union could vote for a strike, limiting service from 6 a.m. to 6 p.m. during the weekdays, and limiting the routes to 3, 8, 11, 16 and 18, according to an article by the Arizona Daily Star.

Negotiations are happening as we speak, facing an 11:59 p.m. deadline today for a final agreement. Discussion between Sun Link and the transit union began June 17, and last week they agreed on a five-day contract extension to continue talks, according to the Star.

TUSD's first day of school is tomorrow, so the district has arranged for additional morning and afternoon routes to accommodate the roughly 2,000 students who rely on Sun Tran to and from school. TUSD buses will not be using the Sun Tran stops, a TUSD press release says. (You can find a list of routes on the TUSD website.) 

Here's more detail on what could be happening tomorrow, according to the press release:

TUSD buses for Sun Tran riders will arrive earlier and depart later than normal. 

The district added 16 mourning buses in case of a strike. The buses should arrive at 6:45 to 6:55 a.m. to the specific schools. 

Afternoon buses are scheduled to arrive at 4:30 to 4:45 p.m, or a little later. 

TUSD will send a message via the ParentLink phone system to families affected by the possible strike by 5 a.m. tomorrow, and will keep them updated throughout.
