I have to work out a tricky situation regarding my employment.
Since the beginning of May I am employed to hiring agency A and allocated to work externally at company B. I don't enjoy this work I am going to look for a new job in the fall. I only took this job because I was allowed to go on vacation for 3 weeks in September, despite the fact that usually that much vacation wouldn't be allowed so early.
Company B is one of the largest companies in the country. Yesterday my superior asked me if I would be interessted to start working at company B directly, because they need to cut down on external personnel by the end of the year.
Since that contract would be 'all in' I would earn more and also get some aditional features like bonus payments. Company A would get compensation from company B.
From my supervisors' perspective this must look like a win win situation for all parties. But with my intention to quit in the fall, there are some finacial downsides for me so I rather won't change company.
What's my play here, to not look too suspicious when declining the offer and not to get cut right away?
