I’m sorry, I mostly agree with the sentiment of the article in a feel-good kind of way, but it’s really written like how people claim bullies will get their comeuppance later in life, but then you actually look them up later and they have high paying jobs and wonderful families. There’s no substance here, just a rant.
The author hints at analogous cases in the past of companies firing all of their engineers and then having to scramble to hire them back, but doesn’t actually get into any specifics. Be specific! Talk through those details. Prove to me the historical cases are sufficiently similar to what we’re starting to see now that justifies the claims of the rest of the article.
The options from other responses are better (gel, cold shrink tubing), but just for your edification, sand in a box can work as an extremely effective insulator for a short period. So heat up the soldering iron and stick it in a bed of sand in a box to take it in with you. Most of the heat won’t escape the box, but it will spread through the tool, so you’ll definitely want gloves.
