I used to work at a restaraunt where we weren't allowed to wear fake nails, nail jewelry or nail polish that wasn't clear. (I think the first two may have been health department regs, but I'm not sure.) One of our mtf transvetites had over-slept and come to work wearing scarlet polish on natural nails. He didn't worry about it because many of us wore colored polish and we all wore latex gloves anyway. He was fired and the asshole, er store manager thought he was safe, hiding behind the rulebook. However, the dishwasher was able to prove that the "no colored polish" rule was not being enforced for the female employees. Since the rule was applied selectively based on gender, the employee was able to successfully sue for discrimination.
As an employer, I wouldn't fire anyone for wearing nail polish. I would, however, fire someone who was more concerned with their nails than in doing their job, which I pay them to do to my satisfaction.
I employ a Goth guy who has his nails shaped like claws & often paints them black or purple. It doesn't interfere with him doing his job, so I don't care.
If, however, I ran a business where personal presentation was an issue, & I had reason to impose rules on my staff for the successful running of the business, then I would expect all staff, regardless of gender, to abide by them. If you don't like my rules, then work for someone else. It's that simple.
Individuality is a wonderful thing, but it's up to you whether you value that more than the job you have. Or, are you pushing a point in order to gain a lawsuit "pot of gold"?
It depends on the job, the country and the individual company policies you live in.
In the UK if the company policies or procedures clearly state the expected 'norm' for working in that eniviroment and you float those policies the following can happen.
Your employer gives you a verbal warning, an additional warning, then a written warning finally you are fired.
Equally if you have been with the company for less than twelve months they can fire you without giving any reason for why they are letting you go.
I used to work in the care industry, I didn't have an issue with nail polish but if someone had nails that were too long or rings with large or sharp stones they were asked not to come to work like that. Equally dangly earrings were against the company policies of the places I worked. Having an earring ripped out of your ear is not a good thing to have happen it is a bugger to get blood and ear tissue out of the furnishings that have been splattered with it.
As others have said, it depends on the line of work. If your employer has appearance standards and you don't follow the rules, then you can be disciplined for not doing so.
I can't wear jewelry to work, but the girls can. (I'm a waiter.) It makes sense, professional attire for men doesn't really allow for large princess cut cubic zirconia studs in your ears. haha.
You know, there is a way to get around it if you're willing to forgo the colored polish. Believe it or not, I actually got my very straight and homophobic father to do this simply because he thought it gave his hands a 'cleaner' appearance.
Buy yourself a buffing kit. Those clean the ridges off of your nails and really gives them a nice appearance. Reminds of me clear nailpolish without the hassel. This is one thing I can do. I'm horrible with my nails and haven't touched polish in ohh...ten years?
