A contractor didn't get paid for 4 months at a previous job because I put the cheques on my boss's desk for him to sign but didn't nag him to sign them, so he didn't. When we finally figured it out, I sent out all the cheques myself and wrote a personal email apology to the contractor.
I have worked for different industries like chemical, fertilizer, plastic manufacturing and oil sands. I have always been successful in accomplishing my job with in-depth knowledge of electrical engineering design and electrical equipment. Even with petrochemical industry, electrical engineering design and equipment will still be the same. Only difference is the implementation of the design, which I would be for sure able to manage with my 25 years of experience.
