Emotional inertia is a key feature of emotional dynamics and it refers to the degree to which a current emotional state can be predicted by a previous emotional state. In this study, using the experience sampling method, we examined the relationship between inertia of negative emotions at work and parasympathetic activity, measured by vagally-mediated heart rate variability (HRV). In line with current literature on HRV, we propose that temporal dependency of negative emotions at work may be associated to lower HRV, an important marker of the ability to flexibly adjust to a changing environment. Participants (n = 120) were prompted six times during a regular workday, while wearing a heart rate monitor. In accordance with the polyvagal theory and the model of neurovisceral integration, findings supported our hypothesis and indicated that workers with lower HRV tend to show high time persistence of negative emotions at work. Practical implications and directions for future research are discussed.
