An anonymous Equinox employee is trying to organize a strike in protest against company head Stephen Ross’ Hamptons fundraiser for Donald Trump’s re-election campaign.

Equinox and sister gym, SoulCycle, faced a firestorm Wednesday when it was revealed that Ross was hosting the event, with celebs and activists freaking out on social media and members canceling subscriptions.

Now we’re told an email was sent to over 1,000 employees calling for workers not to clock in unless Ross, chairman of Related Companies — the gyms’ parent company — cancels the event. The agitators also set up an Instagram account to rally staff to the cause. “We are the cleaners, the managers, the trainers, the group fitness instructors, the sales reps, the shop salespeople, the spa professionals and the gatekeepers,” reads a post. “Our collective efforts will have results. We cannot be silent.” A source tells us, “Managers have been calling all of the group fitness instructors asking them to confirm their attendance” in class.

After the furor broke out, Ross said he strongly disagrees with Trump on some issues, and the gyms said that they had nothing to do with the event.

Meanwhile, other gyms are trying to cash in on their rival’s travails. New York Sports Club, Boston Sports Club and Washington Sports Club are encouraging Equinox members to sign up with them instead and will let them work out for free on Friday, the same day that Ross is hosting his Hamptons shindig. Celeb trainer Tracy Anderson is enticing disaffected Equinox members by promising to donate 20% of her weekend class revenue to Trump-battling charities such as the Human Rights Campaign, Everytown for Gun Safety and the Martin Luther King Foundation.
