Like I said earlier, I think you're going in for full overkill here.
The employer hires an employee, and requires the employee to wear a uniform during work hours, and pays him for it.
There's really not any more to it.
If there's some big thinking behind it, or other parts of the company doesn't wear uniforms, doesn't really matter. If the leadership is braindead or not, they still pay for those 8 hours a day.
If the employee want to change it, it can be done through normal negotiations, until then the employer has the right to decide during work hours.
Oh yeah.... and you get free clothes
