In Sweden, the employer must give you one month notice, and if you quit, you must give the employer one month notice. Refusal to work during this time is breach of contract. When you have been employed for a year or more, this time is extended to 2 or 3 months. Some contracts can even require the employer to give you 6 months notice if you worked for several years, but when you quit, it often doesn't exceed 3 months.
