Manager: (CFO mind you): "You need to be doing X tomorrow at noon"
Me: "Sorry but I can't. Unless you haven't heard... PCI changed the rules as did FINRA within the last 6 weeks. I seriously need to focus on keeping our clients in compliance. Therefore tomorrow I have SIEM + Security projects on the board, you will have to shift X to about 3PM. It's definitely mission critical I remain free tomorrow until 2PM earliest. We need to ensure I understand all I need to know about concepts, methodologies in this field if you wanna keep managed security services in order"
Works all the time... However, it works for me. I'm a stickler on project management (and yes I have studied PMP + ITIL for those wondering). I almost always try to make things a business case since that's all bosses care about at the end of the day. When it makes sense to them financially, you're talking their language. Not trying to explain why you need to understand core concepts and alternatives for pivoting into multiple meterpreter shells
