The trade union Forsa claims people working in the public sector are attending workplaces when not needed – despite public health advice.

The Government says people should work from home unless they are providing an essential service and need to be physically present in an office.

The union claim the guidelines are being undermined by “widespread management failure” to identify workers who should be in the office.

It says there are far too many civil servants required to travel to work to perform their duties.
