Pros
Peers are top-notch and extremely intelligent. Co-workers are very dedicated and work extremely hard. Also found most peers to be very supportive and helpful. The pay is highly competitive.
Cons
It is not my intention to paint a multinational corporation with a wide brush; I'm only referring to my own experience as an LM employee assigned to a US government contract. With that caveat, one must be aware that in the LM Employee Handbook, it states that "employees are expected to work more than 40 hours per week." During my two years with LM, I witnessed 18 (eighteen) people come and go. I have never experienced a professional workplace with such a shocking turnover rate. I worked with dedicated and talented people who went home on a Friday evening and received a phone call that (1) they were terminated and (2) do not report to work on Monday. I also witnessed an entire sub-team of 3 employees turn in their notice on the same day. The majority of resignations were simply due to the lack of work/life balance, employee burn-out, and a management structure that consistently demonstrates a lack of investment in the well-being and success of its employees.
