You need to get your foot in the door and work your way back up again. Don't fall into the trap of thinking any job is beneath you. Watch the movie Pursuit of Happyness. Whatever job you get your foot in the door with will provide you with an opportunity to show you can shine. Remember, you are competing with everyone in the same job title. If you become number one, the best, then they will hire you, provided they have the resources. If it is a revenue producing job, this especially applies. Watch the movie Two for the Money. Also, remember, the only difference between a supervisor and his/her employee are that they have different responsibilities. If you make your supervisor look good to their management, then they should, in turn, bring you up with them. So, no matter what job you get:
1) compete against everyone with your title and become the best by a long shot WITHOUT stepping on anybody in the process.
2) build a relationship with your boss. Find out how they work and change to where you two compliment each other.
3) find out the goals of your boss and do everything you can to help them exceed their goals.
4) throw your ego and your anger out the door. they will get you nowhere in life but in trouble.
5) you have to give respect to earn respect. don't ever let a negative word come out of your mouth. don't get involved in gossip, even if just laughing. don't look down on anyone.
I have a lot more, but I am coming up with a blank. Those tips alone will guarantee you a position at any temp to hire position. Remember, God will throw you challenges to test your faith. Don't think any job is beneath you when are trying to support your family. Adapt and learn as much as you can and most importantly, revel in the journey!
Good luck to you and your family!
Keep Smiling!
