Atypical working hours can be a risk factor for workers. In fact, the body is subject to a circadian rhythm, which affects numerous physiological activities. These biological rhythms reflect the need for certain physiological activities to occur at a specific time of day. This cycle can be disrupted and shifted by external factors. This disruption of biological rhythms can manifest itself in the appearance of health effects. The innovative nature of our work lies in the search for an alteration in psychomotor functions in nursing staff (subject to atypical working hours). To this end, we decided to study the concentration of care workers using a reflex-based psychomotor test, the Psychomotor Vigilance Test (PVT). Other factors will be studied in order to assess the factors that may affect this test.
Population : All care staff in the emergency departments of the participating hospitals: physicians, residents, nurses and nursing assistants. The main objective is to evaluate concentration in medical/non-medical staff at the start and end of a work shift. To this end, we will evaluate the Psychomotor Vigilance Test (PVT) and its variation at the start and end of a shift in these personnel. The endpoint is the difference in reflex time to a visual stimulus performed at the beginning and end of the shift with a 3-minute PVT Test. The first secondary objective is to analyze the number of PVT errors. The criterion defining an error is a reaction time greater than 500ms. The second secondary objective is to compare the PVT and its variation in certain subgroups. The subgroups compared will be defined according to the following criteria : * Shift duration: Non-medical staff (\<10h, \>10h), Medical staff (6 to 10h, 10 to 15h, 15 to 24h) Staggered shift: start before 6h or end after 22h, * Type of service: acute care, MCO, SSR (or emergency sector) * Sleep quality (Pittsburgh Sleep Quality Index), * Professional fatigue (Maslach Burnout lnventory), * Anxiety (French official version of the PSS-14), * Chronotype (Morningness-Eveningness Questionnaire).

T0 - at the start of the shift: completion of the 1st PVT / socio-demographic and workstation questionnaire T1 - at the end of the shift: completion of the second PVT and questionnaire on the course of the shift that has just taken place T2 - 1 week after the end of the shift: additional questionnaire sent with scales to assess work-related fatigue (MBI), anxiety (PSS), sleep quality (PSQI) and chronotype (MEQ).
