Rush Approach
Lets say you are employed at a company for 5 years and have 3000 hours time on type.
Someone else joins your company and has only been there for one year, but has 5000 hours on type due to experience from his previous job. Are you saying that they should get rid of you and keep the newer guy for having more hours on type than you even though you have longer length of service.
Last in first out seems fair to me.
