Effective IT habit No. 10: Go public
The more people who know and rely on you -- especially outside your department or organization -- the harder it is to fire you, notes Engel.
If you have a client-facing job, you're less likely to feel the ax on your neck because companies don't generally like to fire people who have relationships with key accounts, he says -- provided, of course, you obey Rule No. 9.
If your job doesn't bring you into regular contact with clients, you can strive to become well known across different departments, especially in larger, more siloed enterprises.
"Look for projects and opportunities that cut across departments because this builds your internal network -- thus making you more valuable to the company," he says.
