On 25 January 2024, the Microeconomics Unit[1] of the Competition and Markets Authority (CMA) published a report examining competition and market power in UK labour markets (the Report).  The Report is the Unit’s first published work, covering developments in the labour markets over the last two decades.  Over this period, labour markets have changed significantly through the rise of flexible working and the gig economy (defined as labour services contracted through digital platforms), changes in restrictive covenants (contract clauses that restrict what workers can do after they leave their current employer), and shifts in pay-setting policies.  Each of these factors has the potential to impact employer market power.[2]
