Pros
Laing O'Rourke has a lot of work in hand, making for secure employment. They did have quite generous travel allowance, but I hear this has been largely wound back.
Kontras
I worked on a project in Central London with the Expanded arm of Laing O'Rourke as a site/setting out engineer. Even though I was contracted for 40 hours a week, I never worked less than 55 and averaged 58 (Not including saturdays). I often had to miss meal breaks and was never financially reimbursed for any hours worked over the 40 during the working week. This was for £27,000 a year. Though we were paid overtime on weekends, I was told I would only need to work every second Saturday. I was pressured into working about %75 of saturdays and usually asked to work every weekend. In my time there, one of the young site engineers was off work due to stress, which wasn't surprising due to the conditions we were working under. The safety on site was also very poor, there was very much a production first mentality. Planning was ad hoc, making work very stressful and difficult to plan ahead.
