W takim razie czy to jest stawka dla mid/seniora zgodna z UK standards? :smirk:

@addendum a powinna byc ? (opis poprawiony)

Nie wiem czy powinna być ale skoro już się tak powołujesz na ‘UK standards’ to może konsekwentnie w każdym punkcie i w obie strony? :wink:

UK working standards nie maja nic wspolnego z wynagrodzeniem :slight_smile: wynagrodzenie zawsze jest powiazane z rynkiem na ktorym jest oferowane i decyzja biznesowa. kiedys sie nauczysz :wink:

Spokojnie, już się nauczyłem pracując zdalnie i na szczęscie nie wszędzie tak jest, ale może kiedyś się nauczysz :smiley:
