You have a co-worker. Each of you works 8 hours to perform a job/task. They are different task but each of you is capable of doing the others task. For your work, you are paid.
You figure-out & invent a way to get your work done in only 2 hours...so you only need to work 2 hours go accomplish the same productivity.
1) Should you do 2 hours of your original task and then be expected to spend another 6 helping your co-worker do theirs?
2) Assuming you go home after your 2 hours, does your boss have the right to now pay you only 1/4 the amount previously paid because you are now only working 2 hours instead of 8?
