Just learned of the resignation of a colleague, “effectively immediately”. I was not real close to him, but I had worked with him occasionally on several projects. AFAIK, he was generally liked and respected, and the work he was involved in, e.g., security and disaster recovery, is fundamental to our business. So my first thought on reading the announcement was:

WTF???

My second was:

That is one more vacancy between us and layoffs!
