HSA and HRA

I have a high-deductible health insurance plan (grandfathered from before Obamacare).  I fully funded my HSA for 2018 back in February.  It is June, and I have just taken a new job.  The employer is offering an option of an HRA in lieu of health insurance.  My employment may only last six months, and don't want to drop my grandfathered policy (it's a FAR better deal that anything offered under Obamacare).  Can I take the HRA the employer is offering?  Or, does the fact that I already funded my HSA for this year prevent me from having the HRA, too?   It is $1,000 cash money to spend on any medical bill that might arise.
