Is regularly skipping the jummah namaz haram (sin)?

if one skips the jumma regilarly (often or almost always), is it haram? Will Allah send them to hell or punish somehow? That is, what the consequences are? More specifically, is there any difference in the answer for a male / female: Is it acceptable for a man / woman to skip Jumma regularly, or just stop attending it? I ask because our university bureaucrats invented a new annoyance for the Muslim students (I am a professor in a non- Muslim country. Many of my students are Muslim): the university bureaucrats now insist on that all students must attend a "seminar", which is held every Friday, and usually in the afternoon or early evening, i.e., at the same time when my students typically are at the Mosque . This implies that attending jumma namaz becomes practically impossible. Thus the students are forced to make a choice: degree and scholarship vs. attending jumma. Such a choice between scholarship and jumma namaz sounds to me much as what in Christian tradition is called to sell one's soul to the devil.That is to explicitly renounce God. Here, the choice between scholarship and jumma sounds to me much like that: renouncing God I for money. Is it that bad sin/ haram , in the Islamic view? am lost as for what to advise my students to do. I cannot advise them haram, and I cannot advise them to drop out from the university.
