At the end of last month, the General Data Protection Regulation (GDPR) came into effect, changing how organisations can use personal information.
The rule prompted a blizzard of messages from companies begging to keep hold of email addresses for their mailing lists, but schools have also had to adapt how they operate.
However, teachers have now taken to Twitter to exchange "bonkers" stories about how the rule is being implemented.
According to one report, parents have been told they cannot put names on school bags because of GDPR.
Another tweeter said they had heard that schools are telling staff not to put labels on drawers.
And letters have been sent home asking parents' permission for their child to be included in class photos going out to other families.
Data protection also posed some problems for a card addressed to a work experience student.
Although some teachers saw the funny side of the GDPR situation.
