At an old job I had, I gave myself a paper cut on a folder. It wasn't a serious injury anything, but I cut it just right so that it wanted to bleed a bit. I went upstairs to get a bandaid and maybe an alcohol swab. Our admin/HR liaison overheard me asking for one and not only refused to let me have one, but sent me to Occupation Health and made me fill out an incident report. Obviously a paper cut wasn't a priority for OHS, so I sat in the waiting room for over 3 hours. Waiting on a band aid. For a paper cut. And of course it had stopped bleeding long before the doctor saw me, but it was a crazy liability thing so I couldn't leave until I was seen. By the time they saw me, I was (justifiably I think) agitated and so the doctor commented that I looked stressed and played 20 questions with me about the sources of stress in my life. Questions like, "Are you having problems at home?" "Ho is your work life balance?" "Does your job fulfill you?" It was all incredibly frustrating and downright exhausting.
Ever since then, I've carried a small first aid kit in my purse. A couple bandaids, alcohol swab, neosporin packets, headache meds, etc. It's come in handy more than once. I recommend it to all my friends and family - many of whom have also started carrying mini kits that have come in handy.
