*Limitations*

There are a number of limitations in this study, including low participation in study components and the involvement of the author in the HWC process. Since the HWC process was a pilot, there was only a small number of representatives in both TA provider and TA recipient roles who participated in this study, and approximately 30% did not participate in interviews. Since the TA provider sample was especially small (seven UIC TA providers and seven labor expert TA providers), attempts were made to accommodate varying schedules and allow for participation in interviews or the focus group at times that best suited the TA providers. For TA recipients, similar efforts were made to ensure that at least one representative from each team (see Table 1) was interviewed to capture the team's experiences. An additional limitation was there were no opportunities to compare findings from this study to another similar collaborative process with multiple TA providers and TA recipients, as similar examples of TA provider–recipient models were not found in the literature.

Another potential limitation of this study is the author's involvement in the HWC as one of the UIC TA providers who helped with the design and facilitation of the HWC process. This presents a potential bias, both due to the author's own involvement and perceptions of the HWC and the potential bias in interviewees' responses to interview questions, given their knowledge of my role in the HWC process. To partially address this limitation, assurances were made to participants that their data would be both de-identified and reported in the aggregate, and would not be shared outside of the UIC research team. Further, another UIC TA provider conducted interviews with the TA recipients who the author interacted with most directly in the HWC sessions. Although the author did facilitate the focus group with other UIC TA providers, she did not participate in the focus group herself (i.e., she did not share her own perceptions of the HWC process and the role of TA). The author worked with an external colleague to code and debrief transcribed data to both reflect upon and document potential biases and subjectivities.
