I work in a senior position in a small organisation. I'm becoming increasingly tired at how last minute tasks are done. Everything done by deadlines but it's always very last minute which causes stress and and things being done in a rush. I have explicitly said this so many times but things don't change as people are inundated. As someone who works more quickly and more in advance I find it infuriating but I recognise I'm not the most patient with this so perhaps it's my problem. I'm often waiting for other people to do their elements before I can start mine and it causes stress. How do I change this or drip feed the impact?
