What jobs can I do with an English Lit degree besides teaching??Watch
Big one would be content – essentially writing for marketing. If you have any kind of experience writing voluntary articles (eg for the Tab) it can be a help. Look up entry-level copywriter positions (not sure how many will be going at this time). The key is to remember that you're writing not for literary merit but for marketing purposes – to drive a goal – and so your writing is focused around things like the user journey, search engine optimisation and so on as much as quality content.
Consider doing a Masters in Business & Management (MBM). Strathclyde offers a good programme. The advantage of this programme is that it was designed for people who dont have business studies as their first degree; it's built for people like you. Once you get your MSc in Business & Management, you can apply for graduate jobs in any company. No more thinking teaching is the only route for you.
