SOME workers. Which will create even more division among workers, even in the same socioeconomic class. Divide and conquer. That's the extremist way.
I understand exactly where you're coming from. Our office structure doesn't allow for working from home & since bus service sucks where our office is, I drive. So you're correct in stating that I'm incurring expenses that those working from home don't incur and that they will also have available a claim for home office that I don't have. If I had a choice, I would happily work from home but I don't.
As for tax purposes, as long as the employer fills out a T2200 form a small percentage of home office expenses can be claimed if the employer requires you to work from home and you incur out of pocket expenses. However, if these cost are reimbursed by the company then there is no claim to be made.
