Deodorant I understand as some people have asthma. Easier to just outright get rid of it than have somebody keel over with an asthma attack when somebody is spraying it around because they're inconsiderate douche nozzles. Deodorant is also banned in my workplace for that exact reason, at least 3 people I know of there having asthma.
And whilst it's very unlikely to actually happen, they're also easy to use as something dangerous, either through pressure, an idiot with a lighter or the stupid "deodorant challenge" from not long back. You can also get high from it.
As I say, it's not likely to be an issue...But in a world where schools are getting targeted for absolutely anything and everything by idiot parents and sensationalist media, it's easier to just ban stuff where potential lays and bubblewrap the kids rather than face the possibility of losing jobs.
Just get a roll on deodorant. I would be very surprised if your school bans roll on deodorant as that's generally an acceptable alternative basically everywhere else that bans sprays.
*3 Uniform Violations = suspension. But UN-TUCKED SCHOOL SHIRTS count as ''violations''
Well...Yea, my school had that exact same "3 strike" rule. Not following the rules is a violation of the rules, that's how rules generally work.
Remember, school is supposed to be preparing you for adult life
(up for debate how well it does that, but different topic) and what do a lot of work places have? A dress code. It's a simple rule that doesn't hurt anybody, but it's a rule, and if you can't do something as simple as tucking in your shirt then you obviously can't follow rules. Back to the 'work' thing, you'll get a lot worse than a suspension for continually not following the dress code because, as you've probably been told in school, "you're representing the company and we don't want to give the impression that we employ dirty scruffy tramps who don't give a ****"
(not my words).
Just tuck your shirt in.
Not being able to wear short sleeve shirts and skirts/pants being gender specific I have and never will understand the logic behind and ARE stupid rules. I can write an essay on why those rules are ridiculous, but the first two have more than understandable logic behind them.
