@FlyingCatGirl I don't think anyone is suggesting these salaries are the norm across the UK jobs market- of course they aren't. People are saying they are possible, and giving examples of sectors and roles where they are more prevalent, in response to an OP who asked specifically about that. OP went on to say that she also needed to think about what kind of life she wanted outside work, as this might have a bearing on how hard she was willing to push for one of those high salaries. Some posters wrote about extreme work pressures and stress, others' experiences were easier once they reached senior positions. Most I guess are somewhere between the two. For instance. I worked v long hours in previous roles, but now long hours have been replaced by carrying a lot of risk, mitigated by independent subject-specific experience, and I'm able to work from home (a very long way from London and the SE).
In terms of the safety industry, it's really important, and good employers recognise the need for people to be safe at work and get home safe. That's likely to mean the sector is structured as a broad-based triangle with a safety professional as thevSME in many work places, cluster leads line managing these and a much smaller number of higher paid Directors of Safety taking a strategic view of safety practice, ensuring good policies and practices are in place across wide organisational footprints. I wouldn't ask him, but I'd be fairly sure our Safety Director is earning over £100k, with responsibility for safety in contracts worth many hundreds of £millions. Within this global business there are two layers above him focused on Safety. He earns his salary, not through long hours, but by ensuring the whole business unit has good safety, and this requires top-level analysis, communication and systems skills. He works from home but travels a good bit, and he has two layers of safety professionals working under him- the majority in individual sites and a smaller number running these as teams. He started out as a coal miner in the NW, and has made a great living out of a passion for keeping colleagues safe. He's highly influential and greatly respected in this business.
I'm not trying to teach you about your industry- you know it much better than I ever could. I'm just illustrating how many sectors offer opportunities to earn more as you move from procedural into strategic roles. You clearly have a very good quality of life already and between you and your partner earn well and make a valuable contribution, so you might not want to change anything. I can't say whether you have the aptitude and ambition to earn more in more strategic roles, but those roles do exist, both in your sector and accessible in your home area.
