President Puigdemont issued a televised statement on Saturday where he vowed to come to work on Monday unless “forcibly prevented”.
However, the leader is yet to turn up at the Presidential Palace in central Barcelona.
The parliament has also begun cancelling meetings for today, it has been reported.
It comes as Spain’s state prosecutor called for rebellion and sedition charges to be brought against the region’s ousted leaders over their push for independence.
Spain’s State Attorney, José Manuel Maza, has also called for charges of misuse of funds to be given.
The beleaguered leader faces up to 30 years in prison if found guilty.
Spain’s government assumed direct control of the wealthy Catalan region and dissolved the parliament on Friday. It called a snap election for December 21.
Mr Puigdemont and his pro-independence officials had remained defiant and took part in a vote on Friday that declared Catalonia a republic.
Mr Maza said last week he has ordered Catalonia police force Mossos d’Esquadra to detain him if he turns up to work today. He said that if the local police did not carry out the order, national police would do so.
Others ministers have been able to return to work without incident.
Josep Rull, Catalonia’s sustainability minister, tweeted picture of himself behind at his desk.
He provocatively captioned the photo: “At my desk, carrying out the responsibilities that Catalonia has given me.”
Speaking of the Catalan parliament, Carme Forcadell, was also filmed walking into the Palau de la Generalitat, the Catalonian regional Government Palace, this morning.
Violence broke out yesterday in Barcelona as Nazi-saluting fascists clashed with police at an anti-independence protest.
Chanting ‘Viva Franco’ and Nazi-saluting, protesters wrapped in Spain’s red and yellow flag were confronted by Catalan police officers wielding batons.
And anti-fascists are planning a counter-demonstration for this evening amid fears of more unrest in the city.
Hundreds of thousands of protesters also filled the streets of Barcelona yesterday Sunday, in one of the largest pro-unity marches since the crisis began on October 1 following a symbolic referendum on independence which was deemed “illegal” by the Spanish government.
Speaking exclusively to Express.co.uk on Friday Nigel Farage said: “This is Mr Juncker’s worst nightmare.
“The European Union backed Spanish brutality and turned the Catalans against the EU.
“This makes Brexit look like a Sunday afternoon picnic.”
Downing Street said they did not respect the “illegal” actions in Catalonia.
An El Pais poll on Sunday suggested that 52 per cent of Catalans were in favour of the dissolution of the regional parliament and holding new elections, compared to 43 per cent against.
Toni Timoner, UK spokesman for Spain’s ruling Partido Popular, told CNBC Madrid had public support.
He said: ”Since there was the suspension of the government of Catalonia, everything indicates the return to normalcy over the next few days. On top of that we had the demonstrations yesterday which show there is an ample majority for the steps that the government of Spain is taking.”
