I can also relate with this, back then while i was working under someone, most of the workers tend to take excuse and i end up covering for them or would do both their work as well, only to discover that they are just using it as a way to skip work.I agree with this. Few times my older coworker ask a favor to replace him if I have free time. Alegendy ha have headache but he always 'have' headeche since he don't work anymore. He is laziest teacher in school.
