"... I never received any guidance, training, or support..."

I can confirm this, unfortunately. In more than 20 years I had only five days training: 3 days Flash programming (MacroMedia certified). This was pretty good. 1 day Peregrine. Badest software ever written. This was just crap. One day introduction into "Datenschutz". This was like the Spanish Inquisition. Some day some boss jumped to the conclusion that the employees need some training in English business language. He hired a coach for some weeks. The training was after works at 6 PM. We started working at 6 AM. Plus 24/7. Fortunately my English isn’t so bad. I successfully refused to take part. And luckily it is prohibited in Germany to work 14h a day and then start a 10h on call nightshift. At the end of my "career" someone jumped to the conclusion to introduce a new technology: Liferay. Written in Java. And total crap. They started a project and scheduled it for 3 month. We needed 3 years until it was customized and performed without crashing ever 12h. No real experienced Java programmers in the company. We learned it on the fly, less or more. And it was hard core stuff. I never was so much under pressure as in these days. We asked for support. Hiring a certified consultant. This was rejected. More things come into my mind. More than once I brought my own workstation to my workplace. I used my own reference library. One might say that I payed for my work. Looking back I can say that it was luck when I got fired. But when it happened I was really depressed. See also
