Wedi'i ddatblygu mewn partneriaeth gymdeithasol gydag undebau llafur a chyflogwyr GIG Cymru, mae'n amlinellu cyfrifoldebau holl gyrff GIG Cymru, eu timau gweithredol a'u byrddau, ynghyd â chyfrifoldebau rheolwyr ac aelodau staff unigol i greu diwylliant lle mae 'Codi Llais' yn cael ei gefnogi mewn amgylchedd diogel a lle mae pawb yn gwybod sut i fynegi pryder ac yn gwybod beth yw'r broses a fydd yn dilyn.
Developed in social partnership with trade unions and NHS Wales employers, it sets out the responsibilities of all NHS Wales organisations, their executive teams, and boards, along with those of managers and individual members of staff to create a culture in which ‘Speaking Up’, is supported within a safe environment and everyone knows how to raise a concern and knows the process which will follow.
