In a post on the Local 10 web site, executive director Bill Ross told members to watch for an e-mail about a possible strike authorization vote next Wednesday or Thursday if talks over the next three days don’t result in a new deal.

Ross says the biggest issues are seniority, annual increases in pay, and higher health care costs for what Ross calls “less coverage.”

In response, company spokeswoman Amy Buckman says that a negotiating team is working with a mediator and the Guild to try to resolve those issues.
