just hit pause when game loads and it will skip the intro video <| sep |> IANAL having said that a WhenReally depends on how much fuss you want to make with your current employer . Because my contract umowa o prac says I can resign giving a 1 month period . This is unlawful , you ' ve worked for less than 6 months so your notice period is 2 weeks note all notice periods in Poland are ' full calendar weekmonth '. Note this might not necessarily be an ill intention it ' s just a caveat of the law that might not have went into your agreement . So don ' t immediately think that your employer tries to cheat you at least in this particular case . So to leave on the 10 th , you ' d need to provide your notice by the 25 th of December but do try to do it on a working day instead . If you don ' t want to make a fuss and want to stick with your month notice defined in your contract reminder again IANAL that notice period is not legally binding for you , you have to give it by the 30 th of November in which case consider if they will still go ahead with your indefinite contract . b TaxesDon ' t believe that ' s an option , but you ' d have to speak with an accountant . c SalaryBasically hours you ' ll actually spend working total working hours in January your salary . So assuming you ' ll work 25 and 910 and assuming you have a typical 5 day working week , that ' s going to be 621 ~ 29 % of your salary rough and dirty calculation digest with a pinch of salt .
