PARIS — A labor strike by prison guards around France entered its second week on Monday, as the guards vented anger over their pay and dangerous working conditions, an issue that erupted into the open this month after a string of violent assaults by prisoners.

Adding to those longstanding grievances is the newer problem of radicalized inmates, who account for a small fraction of France’s prison population but whose attempts at proselytization and even violent action have left the authorities struggling to respond.

Nicole Belloubet, France’s justice minister, said on Monday after a meeting with unions representing prison guards that the government would continue to negotiate with them on Tuesday over such issues as pay, security and staffing.

“The difficult working conditions of prison guards absolutely deserve to be taken into account,” Ms. Belloubet said at a news conference in Paris.
