COBRA is just the name of a government program that preserves the existing insurance you were receiving through work. So it is the same coverage, by the same provider. But, now you are paying the full (retail, non-group) cost yourself. As mentioned above, it will probably be more than $1200\month for an individual.
If they will work with you on how your absence is coded on your time card, you might still be able to receive (employer paid) coverage. A few hours of vacation pay, paid out each week, would keep your benefits alive. Some locals have leave of absence, maybe that can get you coded right to stilo receive benefits.
FMLA could get you quite a few weeks of paid coverage.
You probably should have talked to a steward -- you need to, if you are not laid off already.
