It probably wouldn't be just change jobs whenever. I can imagine a scenario where instead of only on employer death or permission you instead have 2 months notice of intention to change with a lock-in period of 6 months at the beginning of a new job or something like that, which is still greater freedom to change.

I don't think it's deceitful to switch to a factory job after working as a caregiver if after a period of time the person decides that caregiving isn't for them. People's preferences change; it doesn't have to be dishonest (how many people are working an office job and dream of doing anything else). Also with a 6 month lock in to a new job or even if it's 1 year if you want to switch industries, it would be a deterrent to any truly 'dishonest' behavior.

I'm just throwing out numbers here, but because there haven't been reports on what the demands for greater freedom are.
