Walkouts are planned for the days leading up to Christmas.
Today is the deadline for industrial action by National Highways, Driver and Vehicle Standards Agency, (DVSA), and Royal Mail employees.
They will continue their strike through Saturday with the support of rail workers from Abellio London bus workers and Environment Agency employees who will launch separate waves.
This strike follows two days of strikes among NHS staff. On Tuesday, thousands of nurses marched out, while ambulance workers joined the picket lines.

As thousands of Border Force members strike, passengers arriving in Britain today will face long queues.
Over 250,000 passengers are expected to arrive at UK airports delayed by walkouts by the Public and Commercial Services union.
Mark Serwotka, general secretary of the PCS union, predicted a “huge escalation” in industrial action across January in Civil Service without ministers.
Today saw a Border Force staff strike, causing misery to up to half a billion travellers who arrived in the UK before Christmas.
According to Mr Serwotka, the BBC Radio 4 Today Programme said: “We believe that the action at borders will be very effective.
“We hope the Government will do the right thing, get around the negotiation table, and pay some money upfront.
“If we don’t have enough money, we will raise it. We have a strike fund so that we can continue this action.
“Our strike mandate is valid until May. We will support this action until May, and we would re-ballot again if necessary.
“I believe that January will see a significant escalation in this action in Civil Service and across other parts of our economy unless the Government gets around to the negotiating table.”
