I see nothing wrong with Sailors wearing NCD's to and from their work. Problem lies with using NCDs as a pair of coveralls and wearing unsafe boots.
Hear me out before you start to jump all over me.
NCD's contaminated with oil, paint, grease even body sweat renders them ineffective in their reasons to be worn, Protection from fire. As for the ironing issue well the COC needs to sort that out.
On to bad looking boots. A pair of steel toes that you can see the steel from are no longer effective protection from falling objects. Read it up in the WCB safety digests.
Unpolished boots, simple fix, hold onto some shoe polish and a brush on the Brow. Dont let anyone leave who has brown boots.
Eventually they will get the hint. The same thing for them comming in except send them home to fix there uniform. Then when they are late discipline them.
Eventually they will get the point.
The problem lies with the COC, they don not care. It is easier to turn a blind eye then it is to enforce the Regs.
Unfortunatly enforcing the regs is a matter of safety.
A pair of coveralls can solve most issues of dirty NCDs at the end of the work day.
Some one will say I am out to lunch and straying outside of my field. Go ahead.
Discipline is well with in my field as is the disgusting look of the Fat lazy people I see in uniforms all the time.
Start to apply pressure to them they will sort them selves out.
Enforce rules of having to wear your S&Ps to work, they still look like slobs but just in a different uniform.
