One who acts with a mechanical mind (who does not put himself really into the work), is stupid, obstinate, cunning, insolent, lazy, easily depressed, procrastinating, that doer is called tamasic.
Gītā 18·28He is obstinate in stupidity, stubborn in error and takes a foolish pride in his ignorant doing; a narrow and evasive cunning replaces true intelligence; he has a stupid and insolent contempt for those with whom he has to deal, especially for wiser men and his betters. A dull laziness, slowness, procrastination, looseness, want of vigour or of sincerity mark his action. The tamasic man is ordinarily slow to act, dilatory in his steps, easily depressed, ready soon to give up his task if it taxes his strength, his diligence or his patience.
