The stars of the ITV2 reality series are said to be considering a mutiny after working for 13 hours in the heat on Sunday, with most of the footage not set to make the final cut.
Cast members including Lauren Goodger, James 'Arg' Argent and Gemma Collins get paid £80 a day to appear in the show, and have said that they have not been given a holiday this year, due to filming their Marbella special last month.
They allegedly walked off the set on Sunday and told producers how they felt about their current work schedule, reports The Sun.
A source said: "A lot of the cast members have been complaining about how hard they are worked for little money.
"On Sunday a lot of them put in a 13-hour day and later found their scenes had been dropped. There are a lot of unhappy stars at the moment."
The Only Way Is Essex returned for its sixth series on Sunday (July 22).
The show continues at 10pm on Sunday (July 29) on ITV2.
