I was underpaid and doing a job I didn't really like, I stuck with it for 6 months and told my boss about it. He didn't do anything about it. Our head of department told us at a meeting that as a young professional, you own your career path. I quit the following month and all of a sudden, my boss was ready to listen to him. I told him it was too late, I own my career path and this isn't good for it.
