Staffing solution company Aristo Sourcing released a report on some of the best known companies in the U.S. that has some of the strangest workplace policies.

Apple’s “No Correcting” policy when it comes to customer interactions. This policy requires employees to refrain from interrupting or correcting customers during their interactions. Instead, Apple tries to foster an environment where customers’ ideas and feedback can flow freely without fear of criticism.

Disney has a “No Costume” rule. It restricts guests (including children) from wearing costumes inside the park unless it’s during special events like Mickey’s Halloween Party. The company says the policy is needed to prevent confusion between guests and official Disney characters.

The New York Yankees baseball team has a “No Facial Hair” policy. Team players are required to maintain a clean-shaven look, with no facial hair allowed except for well-groomed mustaches. The team says its policy aims to uphold the team’s professional image and uniformity, and the franchise has a longstanding policy regarding player appearance.

Amazon’s “No Personal Items on The Warehouse Floor” Policy. In the company’s warehouses, employees are forbidden to have any personal items onto the floor that the online retail firm actually sells. Also, warehouse workers are restricted from chewing gum or wearing lipstick while on duty, and they have to leave personal items like mobile phones in lockers.

The company says this practice is to ensure that employees’ personal items don’t get mixed up with the huge volume of products being shipped from each warehouse every day.

Krispy Kreme‘s “A Free Donut for Every A” promotion offers students a chance to get a free doughnut for every “A” on their report card. The initiative encourages academic excellence and rewards students for their hard work and achievements. Krispy Kreme says its promotion incentivizes academic success and fosters a positive relationship with its younger customers. By offering free doughnuts as a reward, Krispy Kreme reinforces the value of education and creates a memorable experience for students.
