I work in a solo physician’s office — doctor and 12 employees.
We (the staff) are all friendly outside of work as well.
The doctor is quite outgoing and friendly, and his wife is more reserved and quiet (though nice enough when you get to know her, but none of us know her very well).
Most employers rightly believe that a person’s past actions are the best predictor of their future actions, and so your professional past counts for a ton in the hiring process.
You’ve built up a past that’s now functioning as screaming warning sign employers.
I have short work histories with previous employers (10 or more in 7 years).
