I'm a back end engineer and i have been told I'm not working fast enough. My day isn't always just coding there is a huge variety of things that happen on a day to day basis. This manager told me that I'm gonna need to step it up and has laid out a list of goals for me to achieve. I have been doing basically 90% of what's required of me but that isn't good enough. Some days you just work slow or have off days and not everything is happening at the speed of light. Any advice? I'm looking for a job already but eventually I want to just retire and live somewhere cheap. Also his evidence? No real evidence but verbal.
