Say I apply at McDonald's and give the conditions that I wish to work under:
1.No income is withheld from me -- thus I am self-employed.
2.I work like every other worker, but get paid a fixed amount agreed upon.
3.I am responsible for taxes myself.
4.I ask specifically for no benefits other than money.
5.It could be contract-based, but doesn't exactly have to be.
Could an employer legally do this?
