Researching the seminar, Eggleston claims in one exercise men sit in a circle naked and are supposed to divulge a sexual experience when a wooden sex toy is passed to them.
In other activities, men strip, are blindfolded and walk through the forest holding hands with a supervisor.
"(Eggleston) claims it happens, but not every time," said law firm partner Brian Chase. "I've never been there, but I know people who've learned a lot from it. It sounds strange on its face, but if you haven't been there it's probably wrong to criticize it, either."
Eggleston asserts that Bisnar insisted he go, and when he refused, his pay was cut to $10,000 a month and eventually to nothing.
"It was a very abusive environment," said Kathleen Hartman, Eggleston's lawyer. "When he didn't go, everything just escalated."
"Did my partner say, 'Hey, you should go to this seminar?' That's the only true fact," Chase counters. "It was never a job requirement. It was never pushed on anybody."
As attention-getting as the claims are, Chase said they're a red herring.
In truth, those $15,000 payments were actually advances that Eggleston was expected to eventually pay back when he started making commission of case settlements, according to Chase.
After 90 days, the advances would be reduced to $10,000 and then expire altogether after another 90 days, he said.
Eggleston, who worked as a personal injury attorney, and the firm agreed to separate, the firm contends.
Bisnar Chase filed a lawsuit against Eggleston Sept. 13, seeking commission from cases he started in their firm and continued to handle after leaving the business.
Hartman said they are working toward an agreement with Bisnar Chase on that issue. As far as what led Eggleston to leave the firm, a resolution isn't in sight.
"No good deed goes unpunished," Chase said. "This is all going to be hilarious a year from now."
