HELSINKI, Dec 14 (Reuters) - Nokia NOK1V.HE, the world's biggest cellphone maker by volume, said on Tuesday it planned to cut about 800 jobs in its home Finnish market.

The company said in a statement it concluded negotiations with employee representatives on the planned reductions, which it plans to start putting into effect in January.

Nokia plans to offer severance packages worth 5-15 months of regular salary but hopes some of the employees affected will be relocated elsewhere in the company, it said.
