LOS ANGELES - Disneyland employees in California authorised a strike in a union-wide vote, opening the door to withhold their labour from "the happiest place on Earth", the theme park's unions announced.
The unions, which represent some 14,000 Disneyland Resort employees, have been in negotiations with Disney over wage increases and other benefits since April.
Talks have stalled and tensions have grown as some employees contend Disney has engaged in anti-union practices.
Ninety-nine percent of members voted in favour of the strike authorisation, according to a union statement.
It allows union leaders to decide when to call the strike, as well as its duration and terms.
This week, Disney said it was "committed" to continuing negotiations scheduled for Monday and Tuesday.
If the talks go ahead as planned, the strike authorisation vote gives union members new leverage in negotiations.
"A strike is always a last resort for workers, but this strong vote shows that cast members across Disneyland are ready and willing to do what it takes to stand up to Disney’s unfair labour practices and get the contract they deserve," the Disney Workers Rising Bargaining Committee said in the statement.
"Today's overwhelming unfair labour practice strike authorization vote sends a clear message to the company: 'we are stronger together and will not be divided by scare tactics'".
After last year's writers and actors strike paralyzed Hollywood, another major labour movement within Disney would be historic.
Employees at its California theme parks have not gone on strike since 1984, according to the Los Angeles Times.
On Wednesday, hundreds of Disneyland employees, also known as "cast members," gathered for a protest in a parking lot outside the park in Anaheim, a suburb of Los Angeles.
The employees complained of low wages and intimidation used by managers, prompting a complaint filed with the National Labor Relations Board.
The union claims that over 500 employees have been reprimanded, threatened or warned about disciplinary action for wearing a union pin, which depicts a Mickey Mouse glove raised in the shape of a fist.
