Pimlico Plumbers boss Charlie Mullins says his firm is "very likely" to appeal after losing a significant court case.
It comes after the Court of Appeal agreed with a tribunal that Garry Smith was entitled to basic workers' rights, following a heart attack, even though he'd been technically self-employed.
Charlie Mullins told the BBC that Mr Smith had chosen to be self-employed, meaning he was paid twice as much, but then would not receive worker benefits.
