I would recommend that you first contact your employer. It is very possible that their accountant was not able to produce these 1099-Misc reports on a timely basis.
If the accountant simply did not produce these reports, I would suggest that you request that he provide you with a copy of these reports. If the employer suggests that you either forget about it or his accountant was not able to produce these reports, then you have 2 possible ways of handling the situation.
On one hand, you can ignore the 1099-Misc! But these is against the law and if you get an audit, you could heavy fines and penalties for not reporting this income, additionally, if the employer gets audited, you might also get into trouble with the IRS.
You could instead choose to include this income on your personal income tax return voluntarily showing miscellaneous income subject to self-employment tax.
Or, you could report this income on your tax return as a Schedule C income from self-employment actiivities and offset this against necessary and reasonable business expenses. This is the best approach in my opinion!
