Other barn staff (not including managers/directors) are wonderful people, but they deserve better. They offer a sign on bonus, should be a red flag because they cannot get people to stay even with the offered bonus.
Contras
Overworked and micromanaged to an unnecessary extent. You will get snapped at in front of students(who are there for therapeutic reasons and often have a history of trauma) very negative and toxic work environment. There's a reason they can't hire people or get people to stay. Also trying to justify keeping and "training" a problematic horse that only the managers can handle due to his behavior. As a therapeutic barn, it doesn't make sense why they invest in a horse who cannot be a part of the program.
