You were lucky. My first radio job began at age 13 for Richard Eaton's United Broadcasting.
Eaton specialized in ethnic stations, mostly targeting Hispanics or Blacks. I was the token white kid at WJMO and sister FM WCUY in Cleveland. I began by getting coffee, doing some janitorial work (because Eaton would not pay for a cleaning crew) and, after a while, I got paid-by-the-hour work on the FM when the FCC required it do more than 6 PM to 11 PM Monday to Saturday.
Eaton was such a bad owner that there would be months without bathroom supplies as he required detailed "requisitions" from DC headquarters. The manager in Miami got cancer and was fired because Eaton owned the employee insurance company. He finally lost licenses in several markets; the one in DC was lost due to allowing illegal lottery numbers to be broadcast as if they were bible verses in a fake religious show.
In Cleveland, we were on the second floor of a car dealership. Eaton was in a wheelchair in later years, and we'd have a pool where the winner would get all the money if they guessed on which step the staff members would trip and drop him on the stairs when he visited. He never fell, but the pool went to buy toilet paper and soap and cleaning supplies... but we never lost hope.
Later, for only a short period, I worked for an LA owner who made going to work feel like a daily root canal. Sales meetings usually ended with at least one person in tears. Employees would quit by simply not showing up for work.
In another market, I hired some of the best people in all areas by recruiting them from stations where they were treated like slaves or servants, not professionals.
There were both kinds of owners... good and bad.
But your experience is more with staff members, not owners. Overwhelmingly the staff of stations I have been associated with or known through associations, inter-station sports teams and charity events as well as conventions and seminars have been great people, dedicated and human.
In my senior year at the U. of MD, I did an independent study on the WOOK (Eaton's station in D.C.) case, spending a lot of time at the FCC doing the research. Yes, they had a Sunday show on which the "preacher" read "bible verse numbers" that were in actuality lottery numbers. I was never clear whether the station knew for sure this was going on.
When the FCC was about to pull WOOK's license, Eaton did something kind of clever. He moved the WOOK-AM format to his FM station, which had been airing DC's only Hispanic format, and moved the Hispanic format to WOOK's class IV low-power signal at 1340. Eaton's message to the FCC was, "You're going to be killing DC's only Hispanic station." The FCC proceeded to take away the AM license. But while he lost WOOK-AM, Eaton now had a more viable format on the FM at the time when more dials were moving to FM.
Richard Eaton and his son Pierre were said to lean to the crazy side of normal. I read that when Richard went on vacation, he insisted on bringing an ex-wife along with his current wife. Pierre, who managed WINX in a DC suburb, would impetuously fire people and then hire them back.
