What are the rule changes you've caused?
Nothing significant, I've mostly been nitpicking wording. First one was about a rule that said you have to deliver doctor's notes related to your absence within the two weeks of the beginning of your "continuous period of absence" (best translation I could make), which is plain stupid and impossible for people who are, say, sick for more than two weeks. Of course, while nobody with half a brain used it as written, administrators relished in it, and that's enough for me to care. This one was actually elevated from departmental to uni-wide status because it appeared almost everywhere independently. Background for it is at best speculative, though. Both second and third were about the allocation of hours and courses (and payment for what goes above your 180/300 ETCS quotas) having some generous loopholes. I like to think I took such a massive advantage it was enough for uni to care, but that's just me having boring dreams.
YW. At present I am mostly surrounded by people who feel powerless, impotent, paralyzed and ineffectual. People who act based on the belief that they are unable to make any appreciable change in their environment. You are capable of making changes. You are a capable person and I know that I'm not the only one who appreciates that about you.
