On the morning of Monday, September 12, 2022, Kai-Lin Chang was riding his bicycle on Victory Boulevard in West Hills when Dr. Brittany Doremus, a palliative care physician employed by Southern California Permanente Medical Group (SCPMG), made a left turn across his path while pulling into a dry cleaner’s parking lot to drop off her children’s Halloween costumes. Chang collided with her vehicle and was hospitalized with injuries. He sued both Doremus and SCPMG, alleging Doremus was acting within the scope of her employment at the time of the accident and that SCPMG was therefore vicariously liable under the doctrine of respondeat superior.
Doremus’s work schedule was not a simple nine-to-five arrangement. On Mondays and Tuesdays she worked at her office at the Woodland Hills Medical Center. On Wednesday mornings she could work from home, on Thursday and Friday she worked with patients at the medical center’s hospital, and when on call on nights or weekends she worked from home. SCPMG also provided its physicians with employer-issued cell phones equipped with special communication software. On the morning of the accident, Doremus testified she had left home around 8:30 a.m. to drive to the office and was on a purely personal errand — dropping off the costumes — when the collision occurred. She did not recall being on any call before the accident. Following the collision she called 911, then sent a group text to the nurse and social worker on her team to cancel her appointments for the day.
SCPMG produced a text message log from Doremus’s wireless carrier showing no texts between 8:30 and 8:44 a.m., with a cluster of messages beginning at 8:44 — the post-accident notifications to her coworkers. A call log showed no work calls before the accident.
The trial court granted SCPMG’s motion for summary judgment. The court found the going and coming rule plainly applied: Doremus was commuting to work on a Monday, as she did every week, and was in the middle of a personal errand — wholly unrelated to her employment — when the accident occurred. The court found no recognized exception to the rule applied: Doremus was driving her own personal vehicle that SCPMG neither provided nor required, she was on no special errand for her employer, and SCPMG derived no incidental benefit from her use of the vehicle. The court overruled Chang’s evidentiary objections to the call and text records, noting that Chang himself had relied on those same records in his opposition. Chang appealed.
The Second District affirmed summary judgment for SCPMG in full in the published case of Chang v. Southern California Permanente Medical Group Case No. B340770 (April 2026). The court awarded SCPMG its costs on appeal. The opinion was originally filed April 9, 2026 without publication, then certified for publication on April 28, 2026, with no change in judgment.
SCPMG met its burden of proof; Chang did not meet his. The court emphasized that in respondeat superior cases involving driver testimony, an employer does not have to eliminate every conceivable possibility of work activity — sworn testimony that the driver was not working is sufficient to shift the burden. Doremus’s deposition testimony that she was commuting on a personal errand, not on a call, and driving her own vehicle accomplished exactly that. Chang then had to offer admissible contradictory evidence, and he failed to do so.
The “hybrid worker” argument failed on the facts. Chang’s more novel contention was that because Doremus sometimes worked from home, her home had become a second worksite, and her Monday morning drive was therefore transit between worksites rather than an ordinary commute — placing her within the scope of employment. The court rejected this categorically. Doremus worked at the medical center on Mondays without exception. Even accepting the premise that a home can become a second worksite, it is only a worksite when the employee is actually working from home — not as a permanent all-day status. On Monday mornings Doremus was not working from home; she was driving to the office. The court found that none of the cases Chang cited — including Wilson v. Workers’ Comp. Appeals Bd. (1976) 16 Cal.3d 181, 184, Bramall v. Workers’ Comp. Appeals Bd. (1978) 78 Cal.App.3d 151, Zhu v. Workers’ Comp. Appeals Bd. (2017) 12 Cal.App.5th 1031, and State Ins. Fund v. Industrial Commission (Utah 1964) 15 Utah 2d 363 — supported the proposition that a hybrid worker’s home is a second worksite on days when she is not working from it.
Workers’ compensation cases are the wrong measuring stick. The court also noted — pointedly, since Chang had himself argued below that workers’ compensation cases had “no applicability in tort cases” — that the going and coming rule as applied in tort is more restrictive than in workers’ compensation. Citing Pierson v. Helmerich & Payne Internat. Drilling Co. (2016) 4 Cal.App.5th 608, 619, the court observed that workers’ compensation law resolves any reasonable doubt in the employee’s favor, a policy tilt that does not carry over to third-party tort liability against employers.
Policy reinforced the holding. The court offered a final, practical observation: ruling for Chang would effectively abolish the going and coming rule for any employee who sometimes works from home, creating a perverse incentive for employers to curtail workplace flexibility to avoid expanded tort exposure. The court found no sound policy rationale for that result.
