My ‘office job’ certainly wasn’t 9-5 and did involve site work too – it was a reasonable salary of £40k+, company car and other benefits. To a degree I was my own boss and ended up in my position as a Contracts Manager from initially being out on site as a skilled op and working my way up.
In the end it ground me down, partly due to myself and the way I managed things, but largely due to the actual working environment. I’m now back doing what I do best and wouldn’t go back. Fortunately, I am now my own boss of two businesses and I get paid very well for standing in a shitty hole at the side of the motorway.
Downside – the supervisor working for the company I work for spent half the night covered in blood, helping walking wounded whilst the emergency services attempted to cut a mangled lad out of a car that had come through the works and rolled 50mtrs down the motorway on it’s roof. Not sure how he, or his pregnant g/f are doing – here’s hoping they are going to pull through 🙁 Fortunately none of the gang working nearby were injured, but it’s a dangerous environment.
