Here's my story. I worked with a startup on its early stage 2 years ago and did pretty good. I was laid off after a year since they want an in-house developer but during my last day, the CTO/Co-founder praised me for my excellent work and thanked me for my work. He also told me that if I needed a LinkedIn endorsement, he'll write me one. At that time I didn't have a LinkedIn account.<p>Fast forward today, I'm asking him the recommendation he told me before. If you're an employer/manager, is this rude to ask?
No, not rude at all. Go for it. The LI system is one of the best ways to facilitate asking for them and collecting them. An extra vote of confidence needed by third parties if you choose people who can genuinely speak to your skills.
