Don't Have a "Screw It" Attitude
--Give your employer any ammunition to use against you
--Report to work late or leave early--especially on a regular basis
--Forget to double-check your work, etc.
--Take the bait (e.g., people will try to antagonize you to get an angry response that can be used against you later)
--Forget to document everything
--Keep your evidence at work where it can be found and destroyed
--Believe you can confide in all of your “trusted” coworkers/pals (people have agendas)
Try to be as smart as possible about surviving the workplace and remember that you may want to pursue other options at a later point, including contacting a lawyer or investigator.
Don't help an employer build a case against you!
