Trust in supervisor positively predicted psychological meaningfulness (B=0.091, SE=0.021, t=4.336, P<0.001), psychological availability (B=0.075, SE=0.025, t=3.014, P=0.003), and psychological safety (B=0.088, SE=0.022, t=4.082, P<0.001). Psychological meaningfulness and psychological availability were positively related to employee engagement (B=0.559, SE=0.080, P<0.001; B=0.412, SE=0.070,P<0.001), whereas psychological safety was not significant (B=0.066, SE=0.021, P=0.225). Boss phubbing negatively predicted psychological meaningfulness (B=&minus;0.055, P=0.008) and psychological safety (B=&minus;0.067, P=0.002), but not psychological availability (B=0.021,P=0.704). Trust in supervisor partially mediated the relationships between boss phubbing and psychological meaningfulness and psychological safety, and fully mediated the relationship between boss phubbing and psychological availability.
