The Facts Behind the Dispute
The case arose from a long-standing working relationship between cousins Joel Ward and Ren Bishop dating to the 1990s. Ward performed general construction work for Bishop Construction, LLC, including building, plumbing, electrical, framing, roofing, and siding work on projects in Idaho, Montana, and Wyoming. Bishop agreed to pay Ward $10 per hour, later increased to $12 per hour, plus one-way travel expenses. Between 2017 and 2019, Ward worked over 1,100 hours but was never paid, totaling $12,443.54 in claimed damages.
