It's your 2nd week in a new job at a company you've been at since May 1st

Check it out fast and ask where do I sign? You owe your employer loyalty and a full honest day's work as long as you are accepting their pay check. You do NOT owe an employer your life, if there is no contract. If the situation was reversed and they had to leave you behind in order to get ahead, how long do you think they'd hesitate?

Say bye bye

I would consider taking it after I found out if it had a good work environment.

Make sure its 40hrs and check benefits
