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?
A high static number, like $100/week. The people who live closer will get a little extra and that's fine (a mild incentive)
This is how a lot of companies in my area do it. They might offer either a transit card, a parking pass, or a small extra cash bonus each month. Generally the transit card and parking passes are more valuable than the cash.
