Administrative weight has absolutely been a factor in companies collapsing. That's an absurd statement.

And as a specific example, the company I work at just does a blanket credit for work from home expenses to every employee to avoid the administrative overhead. Yes it's not a huge admin overhead, but it's one more thing a company has to read and understand the rules on (in each state), enact policies / processes for, and have an employee process reimbursements for.

Frankly, as an employee this just feels unnecessary. I'm already comparing the cost of commuting, work clothes, etc when deciding where to work. The "work from home expenses" end up being less than the "work from an office" expenses, so I'm not sure why California finds it necessary for employers to reimburse one but not the other. It's adding extra complexity for fairly limited benefit (something California seems to be great at).
