I do not believe Employment Status broken down by mutually exclusive Race and Hispanic Origin for the 2014-2018 5-year sample is available in NHGIS (though non-exclusive groups are available, e.g. White only, Black only, Hispanic/Latino). Information on mutually exclusive hispanic groups by race is available for the 1970, 1980, 1990, and 2000 Decennial Census datasets (this forum post outlines how to access those specific tables). Alternatively, Employment status by Race and Hispanic status is available for the 2014-2018 5-year sample via IPUMS USA, though you will not be able to identify individuals by Census Tract due to confidentiality reasons. You could aggregate the data at the PUMA level, however, if that would suit your needs.
