"There are strongly held opinions on the opposing sides of this," he said. "We have not tried to get these recommendations into a package yet."
Mills also said the committee has to take into account the wide-ranging ramifications of their recommendations for the wage levels of other University employees.
"This has taken longer than of us anticipated. It's a darn spider web and if you hit it at any one place, it bounces," he said.
After the meeting, Bartley said Mills ought not to assume that raising wages for the University's least-compensated employees will cause a ripple effect.
"I wouldn't see there would be a powerful precedent set to jack up the union workers' wages," he said.
Bartley also expressed concern that the debate has become too dominated by concerns of implementation.
"I think that questions about money are steering away from the moral imperative of a social situation which could be easily altered," he said.
