How long should you give a job?

[Steve vRS]

I changed jobs in August, leaving a large organisation and joining a smaller one. My previous company said I could go back if the grass was no greener.

Well, 7 weeks in and it is a bit crap. The pay is good but the work is not as expected and there are other little niggles (expenses, competency of colleagues).

Am I being impatient and should I give it longer or act now?
