Explain this; how is X going to have hundreds of different entities exists on the same platform, using identical equipment, on the same software, in the same uniforms and believe that INDEPENDENCE exists.
X knows without these that their brand will suffer, they will not remain competitive, but with these they run the risks of legal, individual and labor Dept lawsuits.
All I'm saying is that UPS is already providing all these services together. The major problem is that todays technological and customer demands require a uniform service, even more so in the future.
If it was only money involved then yes express would be going ground, however with everything I mentioned there is much more involved than just money.
Don't forget X is setting a very dangerous precedence on a macro economic scale. Regulators watching know that if they are allowed to continue then no industry or individual will be safe from a corporation simply writing a manual (contract)to change their workforce to a contractor model, and benefit the same outcome on a much reduced cost.
