DD is 15. She attends her local school which is about 8 miles from where we live. School is about 2 miles from the town, where there are very infrequent transport links to our village, but in the car it's only about a 20 minute journey. (Need to set context so as not to drip feed). Today DD was with 4 friends at lunchtime, they were all looking at their phones.. See teacher approaching, group put phones away. Teacher sees them & confiscates DD's phone, but no-one else's (DD says this is because teacher knows her because she's in his teaching group, but doesn't know the others, not sure I entirely believe her version of events) & told her to collect from the main office at end of school. 5 minutes before end of lesson another child was given permission to leave early to return a borrowed school tie to the office. DD asks if she can leave early to go to the office as well & told no. DD goes to office at end of school to get phone, knowing she has 10 mins till the school bus leaves. Office staff tell her the phone isn't here it's in x room. DD goes to x room, told to go to y room. Staff in y room tell her to wait a couple of minutes. DD tells them she needs to catch the bus so please could she get her phone back. Buses pick up a couple of minutes walk from main school building. By this time the bus had already left. Staff didn't offer any assistance. There is no other way for her to get home given our/school location. Very distressed DD rings me, so I have to leave work early 40mins away to collect her. I want to be clear I have no issue whatsoever with the phone being confiscated. She broke the rules & faced the consequences of that, but DD told staff on several occasions that she was time limited because she had to catch the school bus & by the time she left they knew she had missed it. AIBU to speak to the school to say I'm unhappy about this? I'm sure the confiscation was in theory the lightest form of punishment, but I'd rather they'd given her a break/lunchtime detention, which is the normal punishment for "minor" infractions of the school rules.?
