Sorry but I feel the same as the others, the incentive to work hard and meet targets should be keeping your job when so many people have lost theirs or are facing losing their jobs, struggling to get buy on lower paid jobs or where partners have lost jobs...I think morale might be more of an issue there!
Ask yourself the question, why should your employer give you additional benefits and incentives for doing the same job they currently pay you to do, especially when I'm sure there are countless people who would give anything to have a job, better paid or at all, and income?
Unless you work in some kind of sales environment, excel at your job, are making a lot of money for the firm or have a highly prized skill and it would be a significant detriment to them if you left etc... you may be on thin ground.
If you have a good work ethic and morale (help get it up yourself as per some of the suggestions above), do your job well regardless of incentives then maybe, in the future when times are better, you might get some of the rewards through earning it.
