A May 2021 TUC report into non-compliance with labour market regulations is available here. Here’s the takeaway:
“To put it bluntly, our labour market enforcement system is under-resourced. There are not enough labour market inspectors to investigate and enforce breaches of employment rights in the labour market.”
It doesn’t include a reference to the failure to provide an eleven-hour break between shifts, or the minimum periods of weekly rest – a big issue in the UK film and TV production industries.
