For me most entry-level jobs have also been exit-level jobs. The idea that you can get in at the bottom and work your way up if you are smart and work hard is complete bullshit as far as I can tell. If you want to be treated decently and have your work valued at work, get recruited as a university graduate or into a skilled position that is hard to fill, and also look for a workplace that has at least as many men as women as workers.
Try to avoid working at a job that has mostly women as workers, even if it is a skilled or qualified job. I have found that these jobs are usually marred by sub-standard working conditions and pay and lots of bitchiness and competition between workers. I put this down to collective low self-esteem based on sexist beliefs. Female managers and business owners show little respect for women as workers, female workers show little respect for female colleagues and these women all seem to have little self-respect, and thus don't leave these blighted jobs. My God, what a breath of fresh air it can be to work among only men!
