You cannot ask for an increase in benefits without making it across the board for everyone in the department, or perhaps company. The people who make such a decision are not your supervisor, but people in the board of directors far up the company chain. If you leave your job, they may never know why.

Also, there is the very common phenomenon of companies promising benefits and then not allowing you to use them.  In my company I am allowed to take three weeks of vacation a year. However, I am only allowed to have a day off if there is someone available to cover my position while I am gone. Every quarter, when I am allowed to put in my vacation request, I bcc the union rep so she can help when the request is denied. (The deadline this quarter for summitting requests is September 12th, for vacation October 1st thru December 31st.)

People who do not have a college education for whatever reason (my mom believed it was for boys only), do not have a lot of choices in employment. I am due to graduate with an AA degree in May, trying not to change benefits and jobs until after then, but I do not think I am going to make it. My position is wearing on me physically too much. When it is time for me to leave, my co-workers and my supervisor will wish me the best, but nothing at the company will change.

Some level of protection for employees is needed at the federal level.
