Some businesses are adding an appealing perk to their benefits packages.  Transit vouchers provide free train, bus and streetcar rides for employees on the company's coin. 

This is a great incentive for employees to use public transit (which is often the fastest way to get to work).  This good-deed works both ways since this expense is a tax write-off for businesses.

If you're an employee working for a environmentally conscious company, ask your employer to consider providing this service.  If you're an environmentally conscious employer, you should definitely consider providing this service to keep your employees happy and encourage them to live more sustainable lives.  The expense is reduced, thanks to the tax write-off, your employees will be happy and you'll be doing more to protect our environment.
