I'm engineering director in Russia. Our labor laws guarantee all permanent employees right to leave after two week notice. Notice could be cancelled by employee at any time during two weeks period. Notice could be made by employee even while employee is on vacation/sick leave, so if you on bad terms with your employer, you could take a vacation, submit notice and leave without transitional period at all.

Only exception for that rules is temporary contract (i.e. for a year). If you have temporary contract, you can't leave without reason. But labor law strictly limits grounds for making contract temporary: basically you have to prove that job itself is temporary (related to concrete project or you filling in for maternity leave etc).
