Despite strong support from trade unions and employment rights groups, some business organisations have expressed concern about such a broad and deep extension of employment protection. Smaller employers in particular have raised anxieties over the pace of change and the administrative burden along with the potential for increased litigation. Others point to the risk that the reforms, however well-intentioned, may not deliver in practice if not backed by proper enforcement and advice infrastructure. The existing strain on the employment tribunal system also remains a major concern, as new rights can only be effective if individuals are able to enforce them in a reasonable timeframe.
