happymum glad the link was useful.
If your employer were to ask for voluntary redundancies, they would have to explain the pay you would get beforehand. It may be just the basic statutory redundancy pay (what you are entitled to by law), which is usually 1 weeks pay for each complete year of service, with a couple of age-related variations, which you will have seen on the link. The statutory 'week's pay' which you get by law is limited to no more than £310 though, so for anyone who normally earns more than that per week, they would only get £310 for each complete year of service. Your employer may decide to pay a bit more than the statutory minimum, but they would need to explain this to you first.
They may ask for volunteers for redundancy first. This may be in a situation where they don't want to force people to take redundancy, and would often be where they don't particularly mind who goes. This could be in a situation where, for example, there are 10 people doing the same job, but they will only need 7, so they ask for 3 volunteers. There are two problems with this - firstly more than 3 people may come forward, and secondly, by asking for volunteers, the employer might find that the people it would rather not lose come forward - most employers would rather choose I would think. If they ask for volunteers they should give you information about what will happen if too many people volunteer.
Instead of asking for voluntary redundancies, many employers prefer to have what are called 'forced redundancies'. People will then be selected for redundancy, based on criteria such as what jobs are needed/not needed, things like performance, attendance record, skills the person has, sometimes length of service as well.
There is a possibility they may just identify some jobs which are no longer needed, in which case those individuals will be made redundant. Or they may restructure jobs so that people need to apply for the new jobs, and might have an interview to see who gets the new jobs. The unsuccessful people would then be made redundant.
I think you need to wait and see what happens. At the moment redundancies are only a possibility. If it does come to that, your company will have to explain to everyone how the redundancies will work, who it will apply to and what package will be involved, so you would always know first.
Just something else to add, if you've been there 10 years, your redundancy package would be expensive, so your employer may well want to avoid making you redundant unless absolutely necessary.
Wait and see what happens and what information you get, then come back here if you would like any of it explained further.
