Non issuance of form 16

Dear Sir/ madam,

I have worked with Karur Vysya bank for less than a year and they are objecting to the issuance of form no . 16 to me stating that no such form is issued when the income is less than income tax limits. Here are my following questions :

1.  Is it legal on the employers part to not issue form no 16 under such circumstances ?
2. I worked there till october 2010 and now that i have joined another employer , how would i file my income tax for the FY 2010-2011 ?
3. If this is illegal what is the right forum to raise my plea online/offline ?

Regards,

Aman Sabharwal
