INTRODUCTION:  The aim of this study is to determine job satisfaction among personnel of Institute of Emergency Medical Service Split - Dalmatian County in  Split. Daily  in Split   three Team 1 ( T1 - physician, emergency medicine technician -EMT, driver with no former medical  education) and Team 2 ( T2 - two EMT) during 24 hours,  take care of  178000 inhabitants. Their activities are  directed by Medical Dispatch Unit – both for Split and whole County with 455000 inhabitants. 
METHODS:  We made a cross - sectional study with 51 participants - 37  EMS  provider teams and 14 employees of MDU. They fulfilled validated Minnesota job satisfaction questionnaire with 21 question, also answering abot years working in EMS. Answers were offered according to Likert scale from 1 to 5. Arithmetic mean and standard deviation was calculated for each question in both categories. 
RESULTS: In almost all questions MDU personnel showed better satisfaction ( p>0,05 no significant). The only question where EMS teams showed better satisfaction was about praise, acknowledgment for well done job - average 2,7 to 2,6 at MDU, though the both scores are more in less satisfied than in neutral opinion. The lowest score in EMS group was 2,5 ( SD 1,19) (possibility of advancing), and in MDU group 2,4 (SD 1,01)( working conditions). The general job satisfaction was 3,5 ( SD 0,96) in EMS group and 3,6 ( SD 0,76) in MDU group. The highest score 4,2 in EMS was about variety and in MDU group  4,8 about safety of steady employment. Intrinsic components have achieved better score at both groups.
CONCLUSION: MDU personnel has better job satisfaction than  EMS teams working in field. Improving working conditions and communication  might improve job satisfaction in both groups.
