I work for a psych clinic where the head doctor rarely turns down same-day appointments, while his schedule is fully-booked to see multiple patients/15-20 mins. We've slowly bled providers over the course of the last 3 years and haven't really replaced any of them. Turns out, it's hard to hire when you have a reputation for low salaries and nefarious contract negotiations.

Each specialty may have their own story, but we definitely see constant issues of being overbooked AND understaffed.
