Input: Consider Input: Unite was responding to Plaid Cymru's economy spokesman Adam Price, who urged steel workers to reject a move from final salary pensions.
Balloting is expected to begin at the end of January.
Tata said pension reform is essential to a deal that would see Â£1bn invested at Port Talbot over 10 years.
The company made a commitment to secure jobs and production at Port Talbot and its other steelworks in December.
But Plaid AM Mr Price said Tata was being "opportunistic", adding workers should ask it to rethink the offer.
The financial climate around the steel industry has changed over the last 12 months.
World steel prices have risen from $385 per tonne of hot rolled coil a year ago, when Tata announced more than 1,000 UK job losses, to $536 per tonne by August just after the company put the sale of its Welsh operations on hold.
China had been accused of selling surplus steel to Europe at below cost price, driving down its market value.
But last summer, the European Union continued imposing tariffs on foreign imports - with up to 22% levied on cold rolled steel, which is used in cars and washing machines.
And the turnaround plan put in place at the biggest plant, Port Talbot, saw the reported losses of Â£1m a day at the site reduced.
Mark Turner, a Unite union official at Port Talbot, said: "When politicians start making comments on either side, they need to understand what they're doing and the influence they have on people.
"There are personal decisions to make but also the future of the steel industry, there are a lot of things people have to take into consideration.
"We'd like politicians to keep their opinions to themselves for the time being."
Meanwhile, Aberavon MP Stephen Kinnock criticised Mr Price, saying he was "astonished" at his intervention, given the delicacy of the situation.
"This is a very personal decision that the steelworkers have to make, based on a range of factors," said the Labour MP.
"There have been some very impressive proposals from Tata Steel in terms of securing long term future of the works.
"But on the other hand there are some difficult proposals for the workers to swallow in terms of the pension scheme and the workforce should be allowed to get all the information they need and to vote according what they think is the best thing to do.
"It is not right that any politician should be coming in and meddling in what is a very personal decision."

Output: One of the biggest unions at Tata says politicians should not interfere in the workers' ballot over whether to accept a less generous pension scheme.


Input: Consider Input: It is thought the pilots found the trucks parked up together, waiting to be loaded at an oil production point near Hassakeh and Deir al-Zour.
Warning shots were reportedly fired to scare away the civilian drivers, before the destruction of the trucks began.
IS makes large amounts of money from oil it produces from seized facilities.
The US Department of Defense says it will release video of the air raid, which took place over the weekend.
Last week another 116 tankers were destroyed in a previous air strike.
"This was conducted in many ways identical to our last," Pentagon spokesman, Capt Jeff Davis, said on Monday.
"It was proceeded with a leaflet drop to warn drivers out of their trucks as well as a show of force".
Mr Davis said there were no reports of civilian casualties.
The oil lorry strikes are part of Operation Tidal Wave II, a change in tactics on the part of the coalition. Previously, petrol supplies were largely avoided because of the impact on civilian populations.
A US-led coalition began a campaign of air strikes in Syria and Iraq in 2014, after IS took large parts of both countries.
A series of terror attacks in Paris 10 days ago for which IS claimed responsibility have intensified the air campaign in recent days.

Output: A US air strike has destroyed more than 238 fuel trucks controlled by Islamic State (IS) militants in north-east Syria, the US military has said.


Input: Consider Input: Writing in the IMF's new World Economic Outlook, Maurice Obstfeldt said "we could be at a turning point".
The report forecasts global growth this year of 3.5%, up from 3.1% predicted in 2016.
The UK's economy is forecast to expand by 2% this year, stronger growth than any of the major developed economies apart from the US.
The prediction for Britain this year is now only marginally below what the IMF predicted a year ago, its last full forecast before the Brexit referendum.
The figure then was 2.2%.  The revised forecast reinforces the picture of the British economy's performance being little affected by the aftermath of the referendum, contrary to the expectations of the IMF and many independent economists. The IMF does, however, expect the longer term impact on Britain to be adverse.
The IMF also warns of headwinds that could weaken its global projections. The organisation highlights the possibility of protectionism and what the report calls "trade warfare".
However, the dominant tone of the report is rather sunnier than it has been for some time. For much of the period since the financial crisis of 2008 the IMF has worried that the recovery was failing to generate momentum.
This time the IMF sees buoyant financial markets and "a long awaited cyclical recovery in manufacturing and trade".
The rebound in the prices of commodities has also helped dispel fears of deflation, or falling prices, which has been seen as a danger, especially in the developed world. Deflation can, in some circumstances, aggravate economic weakness.
The forecast for this year would be a marked improvement on last year's 3.1%.
It's striking that in the forecast for the larger economies, there are none predicted to suffer a decline in economic activity this year or next.
Even Brazil and Russia, two countries that have suffered from the fallout of international and domestic political difficulties, are forecast to see growth this year, although it's not particularly strong.
China first quarter growth hits 6.9%
Eurozone growth 'nears six-year high'
Inevitably, the IMF identifies possible risks that could weaken its main forecasts. In particular, the report refers to increasing "pressures for inward looking policies in the advanced economies".
The report notes the loss of what it calls middle-skilled jobs in advanced economies as a result of technological change since the early 1990s. There is controversy about to what extent increased global trade might have contributed to those losses.
Combined with the slow recovery from recent economic crises, this has affected people on lower incomes and led to growing disillusionment with globalisation the, IMF says.
The report warns that this could trigger more protectionist policy actions on trade and immigration.
Mr Obstfeldt writes: "Capitulating to those pressures would result in a self-inflicted wound, leading to higher prices for consumers and businesses, lower productivity, and therefore, lower overall real income for households."
The report also says that the increased fragmentation of production processes across countries aggravates the potential economic damage.
The forecast for Britain has been revised up markedly for this year - to growth of 2%, from 1.6% predicted in 2016. That is a stronger than any of the leading developed economies apart from the US, whose growth is forecast to be 2.3%.
The revision for the UK reflects what the report calls the "stronger-than-expected performance of the UK economy since the June Brexit vote".
But the IMF still expects negative effects from leaving the EU including "reduced consumer purchasing power following the pound's depreciation and its gradual pass-through to prices and the impact of uncertainty on private investment".
It also says that longer term prospects have been diminished because of the expected increase in barriers to trade and migration and the potential impact on the UK's financial services.
One decidedly weak area is Africa, for which the IMF describes the outlook as subdued. For sub-Saharan Africa, economic growth is likely to only moderately exceed population growth. That means correspondingly only moderate progress in raising average living standards in the region.
Although commodity prices such as oil have rebounded from recent troughs, they are still relatively low. The Fund says that is holding back growth in oil-producing nations in Africa such as Nigeria and Angola.


Output: The world economy seems to be gaining momentum, according the chief economist of the International Monetary Fund.
