How secure do you feel at your job at Lockheed Martin?

Every 3-7 years you'll need to look for a new position internally and if you're any good, this will be easy. If you received a poor rating during the last rating period you'll want to be well networked with people at other DoD contractors or you'll risk losing your clearance.

If you know what you are doing, meet schedule, and perform well you will feel very secure. They will let you know if you are failing to perform as expected and give you plenty of opportunities to get back to secure footing. You'll know if you are not making the grade.

Most of the time in aviation it's feast or famine if you have a long-term program let's say you like the F-35 you feel pretty secure with employmentif you

Their is no job security because you are treated as expendable

Not much secure, and it make sense.

It's okay
