The way I see it is if a company needs to pay a performance related bonus, then they aren't paying enough in the first place.
The bonus should be that in the unfortunat event of a cut in workforce. The ones who do what they are supposed to do keep their jobs. The rest are in the firing line.
Back in 2013 when Ford closed our toolrooms and press shop, they offered a voluntary redundancy / early retirement programme. But they also promised re-employment. Out of the skilled workforce they ended up with 80 bookmakers over the number of skilled jobs they had available. We all had to have interviews but it wasn't by any coincidence that anyone with a poor and very "regular" sickness record and those that didn't work as hard as they should, or a disciplinary record more or less guaranteed themselves a job on a production line as opposed to getting a skilled placement. It has only been in the last year those people have started to receive training for a new skilled role. They were, however, fortunate enough to be allowed to keep their skilled pay grade whilst working on the production line, but they were warned that if a skilled job became available regardless of what it was or what shift pattern, if they turned it down they would lose their skilled pay grade and be demoted 2 grades to a line workers grade. This would not only have impacted on their future earnings but also their pension too. Regardless of the number of years they had paid into the scheme as a grade 5, if they were to have retired on grade 3 they would only receive a grade 3 pension.
