I've found that people who do this have just told your company they are not worth the money to employ them, and they go in the next downsize. If the sixty days is enforced by being the actual deadline, all the important steps (documentation, testing, future-proofing, extensibility, simplicity of design, etc.) should be done, along with a new set of custom tools to make the same type of job take a week next time it is asked for. By somebody else if necessary. Ironically (?) the best developers build their own redundancy into their work. I developed in a way that allowed another person to get up to speed and take over my work. It informs good design, coding and documentation. I kept that job for over twenty years with several downsizing episodes. Sorry this sounds like gloating, but it was a technique that worked, so I thought I'd share.
