Man of Honour
I started this job 2 and a half months ago and I'm not settled. I'm being treated as a skivy. I feel really uncomfortable in the place and my days drag. I feel like an office junior and I'm not... I'm on the same level as the others. It's a bit difficult to explain but I'm just not happy, I dread going in every day and Sunday evening's are the worst. I've had a constant headache for the past week which doesn't want to give. I've had a word with my manager about how I feel and he basically just told me to suck it up.
That's somewhat less than helpful from your manager however it's possible that this is a sort of test to see how you'll cope and it will get better - there's a question about whether you'd want to work for a company that does this in the first place but just to point out that it may not always be like this.
However if you aren't already I'd suggest putting some time into applying for other jobs, if nothing else it should help you to feel as if you're taking control of the situation and aren't just accepting the current position. I don't know what area you work in but are there any agencies that could do (some of the) job searching for you? It's not ideal in that they'll usually take a cut for finding you the job and possibly an amount from your wages but it may also be the quickest route out of there with a job to go into.
Maybe even consider looking around for any local community groups that may be of interest? Even the local church maybe (mine used to have a social every month which was good).
