Your employer may offer you the chance to volunteer for redundancy. This benefits employees who are happy to move on to another role, ready to retire, or want the redundancy payment and the employer, who can keep on employees who are most committed to the organisation. Sometimes employers offer incentives for taking voluntary redundancy, like extra redundancy pay or not having to work your notice period.
Voluntary redundancy should be offered to everybody equally. If you feel you are being singled out or pressured into taking voluntary redundancy, especially on grounds of a protected characteristic such as your age or disability, you could have a legal claim against your employer.
Just because you volunteer for redundancy, you are not guaranteed to be selected, especially if more people volunteer for redundancy than need to be made redundant.
