We present preliminary results of the variability search among known HgMn stars with the use of TESS satellite observations. Out of 188 stars with high-quality photometry, only 16 turned out to be constant. Variability among other stars may mostly be attributed to eclipsing binaries and/or rotational modulation. In addition, we found 24 candidates for pulsating variables. TESS observatory turns out to be a great laboratory for variability surveys among chemically peculiar stars.
