I totally agree that cellphones on duty is unprofessional, yet my facility is reluctant to address this issue with a policy, it was reported to me that a lab tech drawing blood stopped to answer her ringing cellphone leaving the needle in the pts arm, while both her hands were on the phone, a co-worker who also teaches nursing told me students interrupt his class all the time with cellphone calls and that I should get use to it and get with the times!!!
