Too many people working there for decades, its great but what does it say about the ambition of their employees.
IT management are absolutely terrible, by the time I left I was the longest serving person in my team but on the lowest pay, had an impeccable annual review every year, they just don't know how to look after or reward their staff.
No prospect of levelling up or promotion within. If they want a higher grade staff, they look external.
It's a very white middle England environment. Just look at their IT Management, in all departments, Support, Enterprise, Network, Cloud, Security, etc. I am not saying they are racist, not on the face of it, but the UK IT Senior Management are institutionally very white England.
Diversity and Inclusion is totally flawed, unless you are LGBT. It's great environment to work for if you are LGBT Community, very supportive. In every other way, it's all talk, there is no Fairness that they promise. I was promised a pay rise to put me in line with the rest of the Team, after 18 months of promises it never came!
They don't develop their staff, they are stuck on the same grade for years, there just isn't any plans or processes in place. So if someone wants to develop themselves they have to leave.
Pay is outrageously low, much less then market rate, I left or the next job at almost 45% more, for a similar job, in fact with less responsibility. If you want to attract high caliber people, you don't have to pay them big, just pay fair.
Too much gap between managers and staff. and between various departments. If you need to get something done or escalated, it is so hard to get hold of people. Way too many people in IT that are very egotistical.
