As a bit of background, I work in the IT industry and have been at this company for 3 years (first 2 where I was an apprentice but was given very little support, I was essentially cheap labor). Recently, a colleague of mine left and we have struggled to find anyone else since, meaning I have a bit of leverage and the company would struggle if I left. We currently do 3 days in the office a week and I want to increase my days at home as being in the office is both a waste of my time and money on fuel. I have asked twice to reduce this to 2 days in the office and this has been declined with the typical bullshit excuses. This has lead me to look at other jobs in my field which seem to be a lot more flexible and pay a lot more. Is it at all worth it for me to tell my boss of my plans to leave to see if they will review my pay or me working from home more often?
