I worked as a Press Officer for a few years and then as a Communications Manager.
To work in PR you need to be able to write well and for a variety of audiences. I had to draft press releases, articles, website content, campaign material and social media posts.
I worked in the health and disability sector so we had to be able to understand medical research findings and turn complex research papers into easy to understand news stories.
Also if you are involved in PR crisis management you are the person who will need to sort out the mess when your organisation is facing a risk to their reputation ( anything from bad press, staff going on strike, redundancies...) and spin something positive to journalists. You only have to think about what the government press staff has to come up with to try to spin ministers out of the current mess to think about how stressful that side of the role can be....
We regularly worked on projects with politicians (I did a campaign that involved Boris Johnson taking part in one of our events to my eternal shame...) and big corporate companies as well as celebrities so you also need to get on with a wide range of people.
Usually you also have to provide out of hour cover on a rota as journalists will call you at weekends and the evenings to get a quote or to ask question about a story that you sent out.
Frankly it is not the easiest of job and it does not just involve making friends with a few journalists and smiling at events....
Also some companies don't usually rate their PR and comms teams that much but they still expect to see themselves in the papers and magazines regularly so there is a lot of pressure to deliver.
I do have fond memories of it and it was interesting to work with so many of the national papers but after a while I really did not like being on call and got bored with the unrealistic expectations of senior management.
