"bei PwC anscheinend die alten Lustgreise"

Von der BBC: "Outsourcing firm Portico said "with immediate effect all our female colleagues can wear plain flat shoes". [...] PwC said the dress code issue involving Ms Thorp at its Embankment offices last December was "not a PwC policy"."

Mal abgesehen davon ist es natürlich legal (Vertragsfreiheit), wenn Firmen ihren Mitarbeitern bestimmte Kleidung vorschreiben, kommt nur auf die Branche an. & wer so blöd ist, einen Vertrag zu unterschreiben, in dem so ein Schwachsinn wie Stöckelschuhe vorgeschrieben ist, der ist selber schuld.

Apropos Legalität, der Independent erklärt es so:

"Employers are able to have dress rules for their employees. Dress requirements could be set out in contracts of employment or, more commonly, a relevant policy may be outlined in a staff handbook.
It's often stipulated that a breach of the policy could result in disciplinary action. In certain cases dismissal might be appropriate."
