Representatives of the Broadway stagehands’ union and of the league representing theater owners and producers held talks throughout Sunday night, into the early hours of Monday, in an effort to bring the ongoing strike to a satisfactory end for both parts.

Talks resumed Sunday evening between Local 1 of the International Alliance of Theatrical Stage Employees and the League of American Theaters and Producers and carried out through the night and into Monday morning, as what is evidently a joint effort between opposing parties to find a solution.

As of 5:30 a.m., the two sides had been discussing and negotiating for 19 hours, reports the New York Times, and the meeting continued. The talks were being held at the law firm of Proskauer Rose, according to the paper.

Talks were adjourned just after 6 a.m., according to Bloomberg.com, and scheduled to resume at about 6 p.m., according to Local 1 spokesman Bruce Cohen.

This is the first time the two sides have met for formal negotiations since Nov. 18, when no satisfactory conclusion could be attained during talks. The strike began more than two weeks ago, on November 10 and has led to the shutdown of most of Broadway’s major productions.

Among the main points of discontent between the two entities are a new set of rules and the number of stagehands - scenery and prop handlers, carpenters, electricians, and lighting and sound technicians - required to start a show and keep it running.

The stagehands had been working without a contract since July when they initiated the strike. Twenty-six theaters have remained dark since Nov. 10.

One exception is the musical “Dr. Seuss' How The Grinch Stole Christmas!” which was court-ordered to reopen by a Manhattan judge last week. State Supreme Court Justice Helen Freedman ruled last Wednesday that the musical adaptation of the Dr. Seuss book “How The Grinch Stole Christmas” welcome theatergoers once more. The musical’s producers argued their contract was special and not subject to the strike.

New York City Comptroller William Thompson has estimated the shutdown costs the local economy $2 million per day, while the League of American Theaters and Producers puts the loss at $17 million per day.

According to the Times, theatergoers enjoying Broadway productions during last year’s Thanksgiving Week and the week before bought tickets totaling some $42 million.
