The company must identify the pool of workers to be considered for redundancy. They must also have a selection criteria. This is a matrix which scores, for example, skills, qualifications, disciplinary record, absence etc. Those selected for redundancy would be those with the highest (or lowest) points depending on how the scores were graded. Age must not be considered, nor should absence be considered for someone with a disability. The scores should be available for scrutiny. I have been in tribunal and noticed that the scores had been added up incorrectly and the claimant should never have been made redundant. Nobody had noticed. Please get in touch with ACAS or CAB
