There was a Chief Resident CME that our newly elected chiefs for 2021-2022 went to for professional development.
Biggest pearl for any chief to learn is that "No." is a complete sentence. I was asked to be chief and I declined due to not enjoying politics and admin burden. But, the one thing I have noticed in my program with the current chiefs and with years past are two pitfalls
1) Letting people run over them
2) Taking on more than they can chew - hindering education and wellness
If you are tasked to make the call schedule, there usually is 1-2 that will complain about everything or always ask to switch. Set some boundaries and escalate to the PC/APD/PD if they make things hectic. One chief made it her goal to change 15 things in the program and took every resident complaint as her own and fought against administration to be a resident advocate. Unfortunately, it took up too much time that was previously spent with family or studying. The discipline part can be hard, and this is coming from someone that just wants everyone to get along. Some LOVE the discipline aspect, others hate it, you'll find out which end you fall in the first few months.
