"A smaller core orchestra must be part of any mediated solution," Scott Provancher wrote to union negotiator Tim Zavadil, noting that musicians had previously refused to discuss reducing the number of full-time musicians and supplementing them as needed with freelancers.
The orchestra currently has 71 full-time musicians.
Zavidil told the Courier-Journal that he couldn't respond without a more specific proposal.
Last month, management cut short contract negotiations with musicians and announced that the orchestra would be forced to declare bankruptcy without major structural changes. Both sides have agreed to mediated talks, but a date for negotiations has not been set.
