Hey!
That sounds terrible and unfair to you - having such a good attitude towards decontamination. Its such a shame that you are the only nurse in your practice that puts in effort. If i were you, id try to have a word with the practice manager as it is of paramount importance that the surgery is completely sterile. I work in a practice where i feel similar- that the other nurses don't put as much effort as they should but there's not too much i can do as we don't have a practice manager
and i don't feel like the dentist would take my comments into consideration as i am technically still a trainee. Good luck and i hope improvement comes your way!
