I think you are misunderstanding what the implications of the proposal would be in practice. It says I can increase my hours on my own accord. Cool. I can't leverage my willingness to do so to my benefit because the proposal will make being the counterparty in that discussion illegal. A company may want to hire someone who can be always available, but they can't find that person, i.e. me, because they legally can't make it a job requirement.

I got a perfect score on the SAT reading comprehension section. Thanks for that valuation contribution to the discussion.
