This might be a silly post, but I read a lot of stories and questions people post on here. I just wanted to say I think people should of course feel fine looking for jobs when you still have one. It gives you financial security and leverage. Also you don’t have to disclose it to your employer or put them as a reference. My other thought is, don’t ever feel bad giving notice or changing jobs. Sure you may have worked with some great people regardless of a good or bad situation. But you need to look out for yourselves. Hope this at least helps somebody, like others have helped me.
