This is a weird question - I think you are trying to point out that the employer/employee relationship is not equal.
This is true. The employer always takes a much greater risk to hire you than you take to work there.

Having a bad out come has a greater impact on an individual than say it does to a SME company with 2k employees.
An employee being fired is not that difficult. You can either not list the experience on your resume or take the hit and lower you expected salary. You'll never be un-hirable just because you were previously fired.
And its very easy to fire people for cause - what its harder to do is fire some one for spurious reasons i.e. fired so you can give your nephew the job.
