I was laid off from a different company with access to 18 months of COBRA. Dropbox is offering a third of that. Lots of job searches take longer than 6 months, so the employees are going to be left high and dry right when they need it the most.
For the non-Americans, my COBRA expenses are about USD$2,000/month for me and my partner. I’m paying as much for healthcare as I am for rent. Even so, it’s still financially better to take COBRA than pay out of pocket for my prescriptions.
