Managers have to be able to defend their judgement to those in trust jobs and other positions if they introduce voluntary redundancies.
This is according to director of human resources research and consultancy at the Institute for Employment Studies Peter Reilly, who discussed some of the difficulties bosses can have with the matter.
He explained many may exclude people with certain skills when introducing a voluntary redundancy scheme because they do not want to risk losing certain workers.
However, "the difficulty with that is that you have got to be able to defend your judgement and you've got to have some criteria by which you do it", Mr Reilly stated.
The expert suggested it is, in some ways, easier to force redundancies upon staff, but this may not always be a feasible option.
Mr Reilly's comments come after chancellor George Osborne predicted last week that up to 490,000 public sector workers could lose their jobs during the spending review period.
