Providers expressed that the damage of a derogatory or rude communication style was not easily mended even if supervisors provided good advice. Rude communication may leave permanent negative memories, as a provider described in the mixed FGD: ‘It was my first time to work in that service and they came to supervise. … S/he told my boss “why have you appointed that ignorant [person] there?”. That thing has never got out of my mind until this hour.’ (P3, female, A1 degree)
