Venus in 6th House synastry favors cordial relationships covering professional and business areas of life. The partners are socially active and reach harmony when collaborating in the fields connected to the social and creative aspects, as well as those of medicine, diet, and recreation.
The Venusian personality aspires to bring aesthetics into the Sixth House person’s life and often succeeds due to its refined manners and friendliness, using everything beautiful and spiritual. However, if Venus is afflicted, hypochondriac moods and behaviors are likely.

Venus in 6th House Synastry Explained
Venus in 6th House synastry teaches that having a beautiful wife/husband is not the same as having any wife/husband because you have to comply with the high standards and work a lot in order to put your jewel into a rightful setting. This is how your partner is likely to feel if your Venus is strong and falls into his or her Sixth House.
In essence, Venus in the 6th House synastry raises the following question: will you serve your partner’s beauty (or social success), or will they serve you? It may seem that your partner can truly rarefy both your work and the instruments you use for it; but in reality, they will struggle to help because, in order to do that, they will have to understand the nature of your work problems, which is impossible without some effort while your partner may not mean any effort at all (Venus is not a hard-working planet).
Conversely, using your partner’s social leverage (charm, charisma, diplomatic skills) can be very constructive for both of you should the partner agree to a subordinate role (which may turn out natural for them). This way Venus in Sixth House synastry will not only help you in your pursuits but may also activate your partner’s romantic and social programs. For hard-working spouses, Venus in 6th House synastry is a beneficial aspect: the partner will feel an inexplicable attraction toward you each time he or she sees you working.
