After receiving job offer, I realized that I probably can't work as early as I put on my application. How much later do you think I can push back my start date without it being an issue?
That is up to your hiring manager.
June 11th, 2001 - Gemini 100 VertiGo Rides - 82 R.I.P. Fright Zone, and Cyrus along with it.
Just ask whoever hired you. Steve V hired me, and I realized I couldn't start the date we had planned and he changed it for me, without a hassle or anything! :)
