The provisional regulations passed by the Polish parliament today will:

* Allow factory managers to order employes to do extra work up to 46 hours a week.

* Give managers the right to require six-month notice for job changes by employes. This is a way of preventing a possible rash of resignations or job-switching that was blocked under martial law.

* Forbid enterprises to award new material benefits to workers.

* Empower the government to freeze prices that producers charge distributors and to direct some firms to produce goods considered essential. These rules appear to run counter to the principles of the country's economic reform program aimed at giving individual enterprises greater autonomy.

* Curb the prerogatives of worker self-management councils by weakening the legal effect of formal protests from such bodies and by authorizing the suspension or dissolution of a council if it becomes a threat to "the legal order or the basic interests of society."

* Strengthen a recent law against work shirkers, or "social parasites," by eliminating fines as a penalty and requiring such people--often ex-Solidarity activists dismissed from other jobs for political reasons--to join government work crews.

* Expand the powers of Cabinet ministers to suspend university senates, fire deans, rectors and directors of institutes, and dismiss faculty staff members.

* Limit students to joining youth associations and organizations already sanctioned by authorities.

* Subject teachers and students to dismissal or expulsion for breaching public order or acting against "the interests of the people's republic of Poland."

* Enable authorities to continue to forbid assemblies if officials consider such meetings "threats to public order."

* Permit authorities to dissolve the leadership boards of cultural associations. This avoids the more embarrassing option of dissolving the whole organization, and is a measure that appears directed specifically at the Polish Writers' Union, whose leadership has refused to submit to Communist Party demands for a purge of antisocialist elements.

* Postpone until at least 1986 the development of multiple unions in factories.

Dropped from the government's original draft of the bill, at the urging of Poland's Roman Catholic Church, were several proposed permanent legal changes. But these measures have been put on parliament's agenda for consideration again next week. They would:

* Expand censorship rules to cover academic work, bibliographies, foreign books and union bulletins.

* Introduce penal code penalties of up to three years in jail for people caught circulating "false information" or participating in banned organizations.
