As the main liaison between you and the bureaucracy of the company, your manager holds some responsibility for helping you find training and other resources for career growth. This may be helping you find a conference to attend or a class to take, helping you get a book you need, or pointing you to an expert somewhere else in the company who can help you learn something.
The role of manager as the person who provides mentoring and training is not a universal expectation. In some companies, these areas are entirely managed by a training arm that you can tap into directly. Some companies are too small to have the money to provide much training, or don’t think it’s a necessary perk to offer employees.
Whatever kind of company you work for, expect that you are responsible, for the most part, for figuring out what types of training you want. This is especially true for individual contributors looking for training in technical areas. Your manager is unlikely to just have a list of interesting conferences or training opportunities at his fingertips.
The other way your manager will contribute very directly to your career growth is via promotion and, probably, compensation. If your company has a promotion process, your manager will be involved in it in some fashion. For companies that do promotion via committee, your manager will guide you through the process of preparing your promotion packet — the set of materials that the committee will review. If your manager or the management hierarchy determines promotions directly, your direct manager will be essential in advocating for your promotion and getting it approved.
In whatever way promotions happen, your manager should have an idea of whether you are qualified to be promoted. When you are interested in being promoted, it’s very important to ask your manager for specific areas to focus on in order to get that promotion. Managers usually cannot guarantee promotions, but good managers know what the system is looking for and can help you build those achievements and skills. Again, this only goes so far. At more senior levels of work, opportunities for promotion are much more rare, and your manager may need you to find and propose the achievements that qualify you for the next level.
