I don’t think sven is necessarily fighting the notion that employers want their staff to have a certain “look,” (she did get rid of her pink hair, after all—that does display some pragmatism), it’s the excessively picky stuff that is puzzling.
Bringing up my former employer’s “No Flat Felled Seams” rule again: What sense did it make to have such a rule, when nicely dressed (really nicely dressed, and professionally dressed too) employees are told to change their outfits, while employees wearing poorly-made bullet-proof polyester slacks are acceptable? That makes no sense. My former employer seemed to want us to drice nicely and professionally, and I had no problem with that—but I saw no sense in how they enforced their dress code, especially when most of us had no problem dressing appropriately (even with the dreaded flat-felled seams ;)).
For instance, I was technically wearing denim to work, but since it was the plain-colored denim (black or dark navy) and cut in a non-“jeans” like style (classic trouser design), no one was the wiser, because they looked just as nice as what anyone else was wearing. But had anyone looked closely and seen that the twill-like fabric of my pants was (horrors!) actually a denim-like material, judging from past behavior, they would have told me I couldn’t wear the pants anymore. And how does that make sense? If the pants look good enough and give off the right impression to customers, isn’t that what counts, rather than nit-picky rules? Apparently to some employers, no. Enforcing rules (in a nonsensical way) is apparently all that is important.
