Pluspunten
I worked for Chevron in their Perth office in Western Australia and it was a great place to work. The vibe was relaxed yet professional and most line managers were appraochable and I felt I learned a lot from my direct supervisors. The organization is social and promotes a good work/life balance such as a CWW where you work a 9 day fortnight so every other weekend is a long weekend. The company taked personal health seriously and promotes ergonomic health by installing sit/stand desk stations so you can alternate between sitting and standing at your desk. I learned a lot from my time here and I think it was a good company for early on in my work career.
Minpunten
As with many companies in the oil & gas sector, contractors make up a large portion of their workforce. I think the ratio in Perth was 70:30, 70% of people being contractors working on a day rate. This meant that opportunity for career growth was limited and contractors also don't receive benefits than full time employees receive. Also contractors don't get paid if they go on vacation or take a sick day.
