The labor and employment experts at Proskauer Rose, who have made headlines recently for several high-profile engagements, are advising The New York Times Company on its contract negotiations with the Newspaper Guild of New York. As of Wednesday, the parties are headed to mediation.

The company and the union agreed to use an outside mediator to help break an impasse created largely by disagreements over compensation and pension benefits. The move to mediation—announced in a companywide email by publisher Arthur Sulzberger Jr.—comes two days after more than 300 Times staffers staged a walkout at the company’s midtown Manhattan headquarters in a show of union solidarity, and a day after the Times‘s own negotiating team, led by Proskauer labor management relations group cohead Bernard Plumwalked out of a bargaining session with guild representatives. (Times spokeswoman Eileen Murphy confirmed to The Am Law Daily the move to pursue mediation.)
