If you are close enough to any of your co-workers to dissuade them from participating, I think it would be an act of charity (fraternal correction) to do so, kindly but firmly. The following reasoning is from the Catechism of the Catholic Church:
2115 God can reveal the future to his prophets or to other saints. Still, a sound Christian attitude consists in putting oneself confidently into the hands of Providence for whatever concerns the future, and giving up all unhealthy curiosity about it. Improvidence, however, can constitute a lack of responsibility.
2116 All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to “unveil” the future. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.
2117 All practices of magic or sorcery, by which one attempts to tame occult powers, so as to place them at one’s service and have a supernatural power over others - even if this were for the sake of restoring their health - are gravely contrary to the virtue of religion. These practices are even more to be condemned when accompanied by the intention of harming someone, or when they have recourse to the intervention of demons. Wearing charms is also reprehensible. Spiritism often implies divination or magical practices; the Church for her part warns the faithful against it. Recourse to so-called traditional cures does not justify either the invocation of evil powers or the exploitation of another’s credulity.
Even if they are not Catholic, anyone who calls herself a Christian should see the truth in the following words from Scripture (and if they are Jewish, at least the first four Old Testament references):
“I, the LORD, am your God, who brought you out of the land of Egypt, that place of slavery. You shall not have other gods besides me.” (Exodus 20:2–3)
“Do not go to mediums or consult fortune-tellers, for you will be defiled by them. I, the LORD, am your God.” (Leviticus 19:31)
Let there not be found among you anyone who immolates his son or daughter in the fire, nor a fortune-teller, soothsayer, charmer, diviner, or caster of spells, nor one who consults ghosts and spirits or seeks oracles from the dead. (Deuteronomy 18:10–11)
Thus says the LORD of hosts, the God of Israel: Do not let yourselves be deceived by the prophets and diviners who are among you; do not listen to those among you who dream dreams. For they prophesy lies to you in my name; I did not send them, says the LORD. (Jeremiah 29:8)
For the time will come when people will not tolerate sound doctrine but, following their own desires and insatiable curiosity, will accumulate teachers and will stop listening to the truth and will be diverted to myths. But you, be self-possessed in all circumstances; put up with hardship; perform the work of an evangelist; fulfill your ministry. (2 Timothy 4:3–5)
See to it that no one captivate you with an empty, seductive philosophy according to human tradition, according to the elemental powers [RSV translation: cosmic powers] of the world and not according to Christ. For in him dwells the whole fullness of the deity bodily, and you share in this fullness in him, who is the head of every principality and power. (Colossians 2:8–10)
If circumstances force you to continue working up to the date in question, I would recommend avoiding working on that day, and arming yourself with holy water on your return. Discreetely sprinkle it around your work place.
but I have a hard time just finding a good priest. So anyways my point is this I think I will just pray from a distance.
