I’m in a similar position, been in safety critical roles for 13 of the last 17 years. Had to react to sudden (sometimes dangerous) changes, stay alert for long periods, communicate with god knows how many different people about the same subject etc… I applied for the job based on me believing I’m a good fit for the role.
I won’t lie and say I haven’t seen the salary, but I’m not motivated by money. If I’m comfortable and can look after my family, that’s all I need. Granted I’d be in a great position if I got the job, but job satisfaction comes above the money for me.
I’ve been fairly lucky over the years, but I’ve been in the odd role where I’ve hated getting up for work every morning. I don’t see that happening if I get this job, I’m dangerously close to 40, I’m looking for an employer to see me through to retirement, which from the outside Network Rail could be.
