I got made redundant 18 months ago when the entire Systems Department (around 83 people) was outsourced to two third party companies. My current employer has a much more enlightened approach - yes we use third parties, but the core business knowledge built up over time by us in-house BI/SQL Server developers is retained, and third parties are engaged only when demand outstrips in-house capacity.

So do I feel secure? Well, as secure as anyone can feel nowadays. Additionally, my personal development plan/training schedule is negotiated annually with my boss when we work through my objectives for the year.
