For context, I am a transport planner for a medium sized logistics company in the UK. I have been with the company a year and a half. Hired initially as admin staff (I have previous planning experience for a role I was made redundant in at the start of the pandemic), then moved into planning. I was working up to getting the national average salary for a transport planner, aiming for around this time to ask for that increase. About a month and a half ago I was told I would need to do the container planning going forward. No big deal, the guy who runs that side of the business is sound. The 1st day I turn up for the new role within the business, I find out that the guy who runs it is leaving for a new job (better money, far better working conditions etc) so I have now been lumped with taking over the entire running of the container side of things, and have been doing so for a month now.
I had asked about a salary review when I moved to this new job and was told, it will be looked at when i'm 'up and running'. The day I took over properly I asked again and told them now that staff member has left, I am essentially up and running. Was told they'd see what they could do and get back to me. This morning, after a month of pure hell trying to plug the gaps someone who was in the job 25 years left, I was offered a £1k a year increase. This increase doesn't even bring me up to the national average salary yearly for a normal transport planner, let alone someone who has now taken on the entire running of one side of the business. It was fucking insulting and I have never in my life felt the urge to walk out from a job and just not come back. Instead I will just have to keep job hunting until something comes up, but at this stage, I am very reluctant to even work my notice period should I be offered a new role down the line elsewhere. Why should I bust my balls working long hours every day, including weekends for just a tiny increase? How are companies so out of touch?
