A group of protesters critical of labor practices in Abu Dhabi, United Arab Emirates, said they would resume demonstrations aimed at the Solomon R. Guggenheim Museum, which is planning to expand there. The group, Gulf Ultra Luxury Faction, or G.U.L.F., held several protests inside the museum in Manhattan in 2014 and 2015, which included the installation of fake artworks and the display of long banners.

Such actions would begin again after a hiatus of about a year, the protesters said in an email, because last week museum officials, including Juan Ignacio Vidarte, the deputy director and chief officer for global strategies, told members of a related group, Gulf Labor, that they would no longer meet with them.

“Since the Guggenheim has unilaterally broken off negotiations with Gulf Labor, G.U.L.F. considers that its self-imposed moratorium has ended,” said the email, which was provided by a Gulf Labor member, Andrew Ross. “It will resume direct actions against the museum in New York and elsewhere.”

The museum replied with a statement saying officials had begun meeting with Gulf Labor six years ago but recently concluded that further meetings would be unproductive, and describing the protesters as being fixated on the Guggenheim.

“Gulf Labor continues to shift its demands on the Guggenheim beyond the reach of our influence as an arts institution while spreading mistruths about the project and our role in it,” the statement, which was provided by Tina Vaz, a spokeswoman, read in part. “This threat is more proof of their singular focus on the Guggenheim rather than a sincere attempt to deal with an issue of global complexity that involves many players.”

A Gulf Labor member, the artist Walid Raad, said that the group had been consistent in its demands and accurate in its depictions.

Over the past year Gulf Labor members had attended three meetings with museum officials including its director, Richard Armstrong and senior trustees, to discuss concerns about workers on Saadiyat Island, a luxury enclave being developed by the Emirates government. Most work there is done by foreign migrants, who are required to pay large recruitment and transit fees, critics say. Laborers helping to build a New York University campus there said that they had been subject to police raids, beatings and deportations after going on strike.

Gulf Labor members said they, along with other rights advocates, had provided the museum with examples of contract language that could help address issues related to recruitment fees, wages and the ability to organize. Museum officials have said those areas were beyond their direct influence. Those officials have added that they remained committed to advocating for workers and said that over the past year new rules by the Emirates’ Ministry of Labor and development arm had improved conditions there.

The protests at the Guggenheim have been highly visible. In 2014 demonstrators threw thousands of pieces of fake currency from upper levels of the museum. Two months later they placed their own politically tinged works in a show of Italian Futurism. And last year protesters dropped 10,000 fliers about workers rights from the museum’s spiral rotunda.
