My company wish to make a number of people redundant both on factory floor and office staff. They have asked for voluntary applications and if numbers are not achieved it will be compulsory. The terms for redundancy are only to be agreed with the unionized factory floor, the office staff are not allowed to be part of these negotiations but however are told that it will apply to them too. One of the initial conditions is that any ex-gratia payment will be capped at €600, this mainly affects office staff. Is this allowed or enforceable?
