I apologize in advance for my whining lately. I have posted several times in the past few weeks about unhappiness with my new job change and looking in to switching careers altogether.
To make a long story short- I am in the third week of my new job and I am really just not happy. I feel like the culture is a bad fit and I also feel like they were dishonest with me upfront about flexibility with hours. I had several discussions with the hiring manager before I accepted the position about my need for flexibility. He assured me that this is a family friendly environment and they could be flexible. Now a few weeks in, flexibility means that you can come in at 8:30, but you have to stay until 5:30. period. I didn't hate my previous job, but the environment was becoming unstable due to budget cuts and there was a possibility that I would have to relocate to a different campus adding two hours on to my commute. I took this position as it is close to home and there was the promise of flexibility. I even took a slight cut in pay and dropped to hourly rather than salary. Let me clarify- my flexibility means sometimes coming in from 8:30- 5:00 or 8:00- 4:30. Not really a big deal.
Anyways, the lack of flexibility combined with the fact that I really just don't like the environment is getting me down. The actual job itself is something that I really enjoy and would probably stick with if other factors were different. I am in no position to just quit, nor would I do anything like that, but I am wondering how long I should give it? Should I start looking right away? Should I give it another month or so? Should I have a conversation with management? I don't want to stick in something that I'm not happy with, but I also recognize that I may need to give it more time. Any suggestions? And if I should just quit bitching and make the best out of the situation, you can tell me that to. I can take it

Re: Pretty certain that new job is not a good fit- How long do I give it?
I do think this is a good point above about the definition of flexibility. They may have been thinking your 8hrs per day can happen at different times (within reason) and it sounds like you were thinking # of hours per week flexes as long as you get your work done. Definitely worth a conversation to figure out what they mean exactly by "flexible." But keep looking in the meantime!
