Suppose there are two employees: Alice and Bob, who do the same job at the same factory. Alice has a 10 minute (20RT) commute, Bob commutes 35 minutes(70RT).
If you're the owner of the factory, would you compensate them for their commutes? How would you do it?
yes, I'd clock in and out on the bus. Know where a municipal bus collects fare near the driver? they had a shift clock there to punch in and out.
