This is a 1988 short film directed by Bill Kroyer. In it, a worker constantly tries to keep up as more and more of his co-workers are replaced by robots. Even back then there were worries that computer animation would overtake traditional animation, which eventually became true about 20 years later.
This is an interesting because this gives a clear view of the difference between traditional and CGI animation. The animal characters are all hand-drawn, but the robots were rendered on computer, which was then traced onto cels and photographed.
