I gave two weeks notice yesterday for a company I've been at for 15 years. I moved though the ranks and have been well compensated, but have felt stretched thin and unfulfilled. I found a new career offer in my field that is effectively a different job function than my old job. When I gave my notice, my manager was in disbelief, telling me that I'm a major loss to the organization and that I should have told him what I wanted to do with my career that my current employer could have created the position.
Why do managers and employers think that this is okay? Like if I'm leaving what is the point in telling me that they've been trying to create the position that I'm leaving for, for years. I know the goal is to convince me to stay, but if you've been trying to make a position for years, then make the fucking position and tell your employees that it's available. Then employees of 15 years won't leave for something unavailable.
