A TUC report into an increase in the number of public sector staff doing overtime for free says that will some staff put in extra hours because of commitment to their job, there is also evidence of "bullying and excessive management pressure."
Times are tough for public sector workers. As the cuts bite and fewer staff find themselves having to take on more work, unpaid overtime inevitably grows.
Some of the increase will be down to the professionalism and commitment of staff who want to provide decent services.
But there is also evidence of bullying and excessive management pressure in some workplaces.
It is not surprising that morale is so low across the public sector. Hours are up, workload has increased, pay has been frozen, pensions cut and jobs insecure as public sector staff know that 60% of the cuts are still to come.
