Senior executives and HR are at odds over how to handle union recognition bids under the Employment Relations Act 1999, according to research.
More than half of all companies try to resist recognition through a variety of tactics, despite the statutory framework, according to the study by Cambridge University's MIT Institute.
But the opposition is coming from senior management, not HR.
"Three-quarters of firms resisting unions do so because senior executives oppose recognition. Only a fraction of HR professionals agree," said Sarah Oxenbridge, at a London conference last month.
